Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-55771 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.cedarpolicy:cedar-java (Maven): affected all versions; fixed in 2.3.6\n- com.cedarpolicy:cedar-java (Maven): affected all versions; fixed in 2.3.6\n- com.cedarpolicy:cedar-java (Maven): affected from 3.1.2; fixed in 3.4.1\n- com.cedarpolicy:cedar-java (Maven): affected from 3.1.2; fixed in 3.4.1\n- com.cedarpolicy:cedar-java (Maven): affected from 4.0.0; fixed in 4.9.0\n- com.cedarpolicy:cedar-java (Maven): affected from 4.0.0; fixed in 4.9.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-55771/ (Markdown: https://insights.sbomify.com/CVE-2026-55771/index.md)","id":"CVE-2026-55771","markdown":"https://insights.sbomify.com/CVE-2026-55771/index.md","name":"CVE-2026-55771","record":{"aliases":["GHSA-4r9r-4425-74p7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Java authorization library","requires_auth":"low_privilege","summary":"Incorrect equality logic in CedarJava entity identifiers may allow integrators to bypass authorization checks if they rely on custom equality comparisons.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"},{"id":"CWE-697","name":"Incorrect Comparison"}],"description":"CedarJava is an open source Java implementation of the Cedar policy language, used for fine-grained authorization decisions. In versions prior to 4.9.0, the EntityIdentifier.equals() has inverted null/self branches which could lead to incorrect equality comparisons. The EntityIdentifier.equals() method has inverted logic for null and self-reference checks, returning true for null comparisons and false for self-comparisons. This does not affect Cedar authorization decisions (computed in Rust from JSON), but could affect integrators who perform their own equality checks on entity identifiers.
