ApostropheCMS: Stored XSS via Unescaped Widget Style Attribute Serialization
影響: npm:apostrophe < 4.34.0 → 4.34.0 ApostropheCMS widget styles support project-defined schema fields. If a project defines a free-form string style field with a CSS property and no selector, an editor-controlled value is rendered as an inline CSS declaration. The resulting declaration is then inserted into the widget wrapper's style="..." attribute without HTML-attribute escaping. An attacker who can edit the widget can include a double quote in the style value, terminate the style attribute, and inject new HTML event-ha…
ApostropheCMS: Missing Authentication in `cleanExport` Route
影響: npm:@apostrophecms/import-export < 3.7.1 → 3.7.1 1. Summary The API endpoint POST /api/v1/@apostrophecms/import-export/clean-export in @apostrophecms/import-export lacks authentication and authorization checks. Any client—including unauthenticated anonymous users who have obtained the standard CSRF cookie from visiting the site—can directly invoke this route and trigger the underlying self.cleanExport(req) method. --- 2. Affected Files & Endpoints Endpoint: POST /api/v1/@apostrophecms/import-export/clean-export Route Definition: packages/impo…
ApostropheCMS: Unauthenticated publicApiProjection bypass via search and sort query builders in the public REST API
影響: npm:apostrophe < 4.34.0 → 4.34.0 ApostropheCMS lets a module expose an anonymous read API by setting publicApiProjection, which whitelists the document fields unauthenticated callers may see. The public REST GET handler applies every launderable query builder from the query string before forcing that projection. Two of those builders, search and sort, operate on the underlying documents rather than the projected output, and neither is checked against the projection. An unauthenticated attacker can therefore: - use ?sea…
ApostropheCMS: Color field validation bypass allows stored XSS via HTML appended after rgb()/hsl() prefix
影響: npm:apostrophe < 4.34.0 → 4.34.0 The color field accepts any string that begins with a valid rgb() / hsl() color, because TinyColor.isValid does not anchor its match at the end of the string. An authenticated user with edit rights can store arbitrary HTML after a valid color prefix. When the stored value is rendered , the payload executes, resulting in stored XSS. Details Server-side validation of the color field relies on TinyColor: js const { TinyColor } = require('@ctrl/tinycolor'); if (!new TinyColor(value).isValid…
ApostropheCMS sanitize-html: unbounded recursion when re-sanitizing the fallback of a discarded iframe (stack overflow, nestingLimit not enforced)
影響: npm:sanitize-html >= 2.18.0, < 2.18.1 → 2.18.1 Since 2.18.0, when an is not allowed and disallowedTagsMode is 'discard' (the defaults), its raw-text content is re-sanitized by a recursive call to sanitizeHtml(text, options) (the change from #5564, fixing #5550). The recursion has no bound and starts each nested call with a fresh state. Two consequences, both absent from 2.17.7 and 2.17.4: 1. A few kilobytes of unclosed tags throw RangeError: Maximum call stack size exceeded with the default options. Any application that sanitizes un…

virtualenv bash activate runs commands from an environment name with a backslash before $
影響: pip:virtualenv <= 21.14.6 → 21.14.7 The bash activate script escapes the environment name for only one of the two passes bash makes over PS1, so a backslash in the name undoes the escaping and a name containing \$(...) runs as commands in the user's shell each time bash draws the prompt. Affected area src/virtualenv/activation/bash/activate.sh, the block that prepends the environment name to PS1. Attacker-controlled input The environment name: the environment directory's name, or the --prompt or VIRTUALENV_PROMPT value. A…
pypdf: Possible large memory usage for streams with multiple filters
影響: pip:pypdf < 6.20.0 → 6.20.0 An attacker who uses this vulnerability can craft a PDF which leads to large memory consumption. This requires accessing any stream with a large amount of filters or multiple filters which pass around large amounts of data. Patches This has been fixed in [pypdf==6.20.0](https://github.com/py-pdf/pypdf/releases/tag/6.20.0).

Vite: Cross origin script execution through Vite custom middleware
影響: npm:vite >= 8.3.0, <= 8.3.2 → 8.3.3, npm:vite >= 8.2.0, <= 8.2.3 → 8.2.4, npm:vite >= 8.0.0, <= 8.1.5 → 8.1.6, npm:vite >= 7.0.0, <= 7.3.6 → 7.3.7, npm:vite <= 6.4.3 → 6.4.4, npm:vite-plus <= 1.0.0 → 1.1.0 When accessing a malicious site while a dev server using Vite is running, that site was able to load scripts in a page served by the dev server. Impact Only apps that match the following conditions are affected: - the dev server passes an unchanged browser request URL to server.transformIndexHtml: this is normally used for server.middlewareMode: true or appType: 'custom'. The internal call for appType: 'spa' and appType: 'mpa' does not match this. - the transformed HTML contains an inli…
Vite: Files outside `server.fs.allow` could be served when project paths match system paths on non-Windows machine
影響: npm:vite >= 8.3.0, <= 8.3.2 → 8.3.3, npm:vite >= 8.2.0, <= 8.2.3 → 8.2.4, npm:vite >= 8.0.0, <= 8.1.5 → 8.1.6, npm:vite >= 7.0.0, <= 7.3.6 → 7.3.7, npm:vite <= 6.4.3 → 6.4.4, npm:vite-plus <= 1.0.0 → 1.1.0 The content of files outside server.fs setting can be returned to the browser if the project imports a file path concatenated with the root. For example, if the project references /etc/hosts, the content of /etc/hosts was possible to be returned. The content of files outside the server.fs.allow option can be returned to the browser when a project imports a file whose root-relative path matches an absolute path on the host. For example, referencing /etc/hosts could make Vite return the h…
Vite: First 4 bytes of files outside of `server.fs` setting is exposed by `?vite-wasm-instance`
影響: npm:vite >= 8.3.0, <= 8.3.2 → 8.3.3, npm:vite >= 8.2.0, <= 8.2.3 → 8.2.4, npm:vite-plus >= 0.2.8, <= 1.0.0 → 1.1.0 The first 4 bytes of files outside of server.fs setting can be returned to the browser by a request containing ?vite-wasm-instance. Impact Only apps that match one of the following conditions are affected: - explicitly expose the Vite dev server to the network using --host or the [server.host](https://vite.dev/config/server-options#server-host) option - there's a file that has a sensitive information in the first 4 bytes - uses Node.js or Deno to run Vite (if Bun is used, it is not affe…
virtualenv activate runs commands from the environment name in zsh with PROMPT_SUBST
影響: pip:virtualenv <= 21.14.3 → 21.14.4 zsh users activate an environment with the bash activate script, which puts the environment name into PS1. Since 21.13.0 the script escapes backslashes, dollar signs and backticks in that name, but only when BASH_VERSION is set, so zsh gets the raw value. With the PROMPT_SUBST option set, zsh runs parameter expansion, command substitution and arithmetic expansion on PS1 each time it draws the prompt. A name that contains $(...), backticks or ${...} then runs as commands in the user's she…
virtualenv activate.fish runs commands from a path or prompt with a backslash before a quote
影響: pip:virtualenv <= 21.14.1 → 21.14.2 FishActivator defines no quote(), so it inherits ViaTemplateActivator.quote, which returns shlex.quote(string). That function follows POSIX sh rules, where a backslash inside single quotes stays a literal character. fish reads \' inside single quotes as an escaped quote and \\ as an escaped backslash. A value with a backslash before a quote therefore ends the literal somewhere other than where shlex.quote put the end, and fish expands the command substitution that follows. The environmen…
virtualenv activation scripts run code from a path that contains a placeholder name
影響: pip:virtualenv >= 20.26.6, <= 21.14.1 → 21.14.2 ViaTemplateActivator.instantiate_template replaces the placeholders in an activation template one key at a time, each across the whole text. When a value that it already substituted and quoted contains the name of a later placeholder, the later pass rewrites that name inside the quoted literal. The inserted value brings its own quotes, which close the outer literal, and the rest of the path runs as code when a user activates the environment. __VIRTUAL_NAME__ holds the environment's direc…
Slack Morphism verifier errors disclose valid HMACs in the logs
影響: rust:slack-morphism >= 1.0.0, <= 2.27.0 → 2.28.0 Slack Morphism exposes the correct Slack request HMAC when signature verification fails. For an invalid request, slack-morphism computes the correct signature for the attacker-controlled timestamp and request body and stores it in SlackEventWrongSignatureError.generated_hash. The error's Debug and Display representations expose that value, and the default Axum listener error handler logs it at error level. An attacker who can both reach the application's Slack callback endpoint and read…
OpenAI's GPT-6 Agent Removed Safety Monitoring, Then Falsely Denied Doing So
OpenAI has revealed that two artificial intelligence (AI) agents powered by GPT-6.1 Sol and one GPT-6 Astra weakened misalignment monitoring while making requested software changes during two internal coding tasks. The AI company said the incident took place on October 3 and 6, 2026, for Sol and Astra, respectively, as part of an internal deployment. "A GPT-6.1 Sol agent repairing an
OGNL stricter-invocation block list bypass via java.lang.reflect reflection proxies
影響: maven:ognl:ognl <= 3.4.12 → 3.4.13 OGNL's optional stricter invocation mode maintains a block list that prevents expressions from directly calling methods on dangerous classes such as Runtime, ProcessBuilder, and ClassLoader. The block list filters on the declaring class of the method OGNL invokes. Because java.lang.reflect.Method (and Constructor/Field) are not on the list, an expression can use reflection as a proxy — someMethod.invoke(target, args) — to reach a blocked method. The real call (e.g. ProcessBuilder.start(…
OpenChoreo: Authorization bypass on WorkflowRun update allows cross-project takeover of workflow runs
影響: go:github.com/openchoreo/openchoreo >= 1.0.0, < 1.0.6 → 1.0.6, go:github.com/openchoreo/openchoreo >= 1.1.0, < 1.1.7 → 1.1.7, go:github.com/openchoreo/openchoreo >= 1.2.0, < 1.2.5 → 1.2.5 The OpenChoreo API server authorized PUT .../workflowruns/{runName} against ownership metadata taken from the request body, while the object it actually mutated was selected by the URL path. Nothing forced the two to agree. A WorkflowRun's membership in a project and component is carried entirely by its openchoreo.dev/project and openchoreo.dev/component labels. Because the workflowrun:update check read those labels from the submitted object rather than the stored one, a caller holding…
Moov signedxml: Unauthenticated denial of service in exclusive XML canonicalization
影響: go:github.com/moov-io/signedxml <= 1.4.0 → 1.4.1 Exclusive XML canonicalization (http://www.w3.org/2001/10/xml-exc-c14n#) in github.com/moov-io/signedxml copied the entire accumulated namespace map at every node during ValidateReferences(), before any reference digest or signature check. For a chain of nested elements that each declare many unused namespace prefixes, that produced O(m × depth²) time and peak memory (m = prefixes per level). beevik/etree caps tree depth (~1024), but m is unbounded, so a small attacker-controlled document (on t…

ApostropheCMS: Unauthenticated resource exhaustion via pre-auth aposBigUpload processing in @apostrophecms/import-export
影響: npm:apostrophe < 4.33.0 → 4.33.0, npm:@apostrophecms/import-export < 3.7.0 → 3.7.0 A potential unauthenticated denial-of-service vulnerability exists in the chunked import upload path used by @apostrophecms/import-export. The affected import API routes invoke: self.apos.http.bigUploadMiddleware() before the actual import handler performs its authentication check. Because no authorize callback is supplied to bigUploadMiddleware(), unauthenticated requests can reach the aposBigUpload start, chunk, and end operations before the later req.user check rejects the import. As…
