A flaw was found in Keycloak's Fine-Grained Admin Permissions (FGAPv2) feature. An administrator with limited client management permissions can exploit this vulnerability to assign any realm role, including highly privileged roles, to a client's scope mapping. This bypasses intended security controls, allowing the injected role to be projected into a user's authentication token when they access the modified client. This could lead to unauthorized privilege escalation within the Keycloak realm.

radare2 6.1.5 contains a use-after-free vulnerability in the gdbr_pids_list() function within the GDB client core that allows remote attackers to cause a denial of service or potentially execute arbitrary code by sending malformed thread information responses. Attackers can trigger the vulnerability by causing qsThreadInfo to fail after qfThreadInfo successfully allocates RDebugPid structures, resulting in double-free memory corruption when the error path attempts to clean up the list.

Agent Zero before version 1.15 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by supplying crafted paths to the image file serving endpoint, which relies solely on an extension allowlist while the path containment check is explicitly disabled. Attackers can request any file with an image extension readable by the process, including files outside the agent workspace, user home directories, and mounted volumes, and can also leverage symlink-based escapes due to the lack of path canonicalization in the path resolution logic.
