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(…

A2A Java SDK: Push notification credentials logged in cleartext on protobuf parse failure
影響: maven:org.a2aproject.sdk:a2a-java-sdk-transport-rest < 1.3.0.Final → 1.3.0.Final Impact. Push notification bearer tokens and authentication credentials submitted by clients are written to server log files in cleartext. Any operator, log aggregation system, or attacker with log access can read these secrets and use them to authenticate to the client's push notification endpoints, potentially sending forged task status updates. Where. transport/rest/src/main/java/org/a2aproject/sdk/transport/rest/handler/RestHandler.java:676 in parseRequestBody What. The parseRequestBody meth…
A2A Java SDK: Android synchronous POST forwards credentials across authorities after incomplete redirect fix
影響: maven:org.a2aproject.sdk:a2a-java-sdk-http-client-android >= 1.3.0.Final, <= 1.3.1.Final → 1.3.2.Final The GHSA-9rhm fix added this safe setting in AndroidA2AHttpClient.createConnection(): connection.setInstanceFollowRedirects(false); The synchronous POST builder later overwrites it: private boolean followRedirects = true; public A2AHttpResponse post() throws IOException { HttpURLConnection connection = createConnection("POST", false); connection.setInstanceFollowRedirects(followRedirects); // ... } The second assignment wins. JSONRPCTransport and RestTransport both add interceptor-produced head…
A2A Java SDK has Server-Side Request Forgery (SSRF) in push-notification delivery
影響: maven:org.a2aproject.sdk:a2a-java-sdk-server-common < 1.3.0.Final → 1.3.0.Final --- - Ecosystem: Maven - Affected package: org.a2aproject.sdk:a2a-java-sdk-server-common (push-notification delivery) - Affected versions: /latest/meta-data/iam/security-credentials/. Use returnImmediately: true, header A2A-Version: 1.0, and role ROLE_USER. The URL is stored verbatim. (Equivalent via CreateTaskPushNotificationConfig on an existing task.) 3. As the task emits state/artifact updates, the sender POSTs each one to the stored URL, from the server's own network position: POST /latest…
A2A Java SDK has a fail-open default task authorization
影響: maven:org.a2aproject.sdk:a2a-java-sdk-server-common < 1.3.0.Final → 1.3.0.Final Draft text for GHSA-qw47-mcm5-934w. The body below drops into the GitHub advisory description field; the metadata block maps to the form fields. Set the patched version at release; publish when the fix ships._ --- - Ecosystem: Maven - Affected package: org.a2aproject.sdk:a2a-java-sdk-server-common (task store / authorization) - Affected versions: <= 1.2.0.Final (and 1.2.1.Final-SNAPSHOT on main prior to the fix) - Patched version: _(the release that carries the fix, e.g. 1.2.1.Final)_ - CWE: CW…
A2A Java SDK send client credentials under server-controlled HTTP header name, enabling leakage via redirect
影響: maven:org.a2aproject.sdk:a2a-java-sdk-parent < 1.3.0.Final → 1.3.0.Final Impact. A malicious or compromised A2A agent can cause the client's API key credential to be forwarded to an arbitrary third-party server. The agent serves an AgentCard with an APIKeySecurityScheme specifying a custom header name, then responds with an HTTP redirect. The JDK HttpClient follows the redirect and forwards the custom header containing the credential, since only the standard Authorization header may be stripped on cross-origin redirects. Where. client/transport/spi/src/main/java/org…

JavaCV: Integer Overflow in IPCameraFrameGrabber Causes Infinite-Loop DoS
影響: maven:org.bytedeco:javacv < 1.5.14 → 1.5.14 IPCameraFrameGrabber parses the Content-Length value from the multipart MJPEG HTTP stream returned by the configured IP camera without any bounds checking. A malicious or compromised camera endpoint - or any network attacker able to tamper with the plaintext HTTP response (these streams are conventionally accessed over http://, as documented in the class itself) - can supply a Content-Length value in the range 1073741825-2147483647. This drives the internal buffer-growth routine ensureB…
