An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-112394 exists.\n\nAffected packages and fixed versions:\n- pillow (Bitnami): affected all versions; fixed in 13.0.0\n- pillow (PyPI): affected all versions; fixed in 13.0.0\n- pillow (PyPI): affected all versions; fixed in 13.0.0\n- Pillow (PyPI): affected all versions; fixed in 13.0.0\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-2026-112394/ (Markdown: https://insights.sbomify.com/CVE-2026-112394/index.md)","id":"CVE-2026-112394","markdown":"https://insights.sbomify.com/CVE-2026-112394/index.md","name":"CVE-2026-112394","record":{"aliases":["BIT-pillow-2026-112394","DEBIAN-CVE-2026-112394","ECHO-42fe-1e53-4182","GHSA-4558-3h8r-v8xp","PYSEC-2026-4327","UBUNTU-CVE-2026-112394"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python imaging library","requires_auth":"none","summary":"Attackers can read adjacent heap memory or crash the application by supplying crafted image buffers to Pillow's raw decoders.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pillow","vendor":"python"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-126","name":"Buffer Over-read"}],"description":"Pillow is a Python imaging library. Prior to 13.0.0, Pillow's P;2L and P;4L raw decoders can read past the end of an input buffer. ImagingRawDecode calculates a packed-pixel row size, while the unpackers read separately padded bit planes. A caller can supply a buffer and image dimensions whose accepted size is smaller than the unpacker's actual footprint. This can disclose up to three adjacent heap bytes in output pixels or crash the process.
