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-2026-112896 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-2026-112896/ (Markdown: https://insights.sbomify.com/CVE-2026-112896/index.md)","id":"CVE-2026-112896","markdown":"https://insights.sbomify.com/CVE-2026-112896/index.md","name":"CVE-2026-112896","record":{"aliases":["BIT-pillow-2026-112896","DEBIAN-CVE-2026-112896","ECHO-6c6e-61ed-491d","GHSA-pchr-8j38-3x4p","PYSEC-2026-4334","ROOT-APP-PYPI-CVE-2026-112896","UBUNTU-CVE-2026-112896"],"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":"An attacker can cause heap memory disclosure or process crashes by tricking an application into re-encoding a crafted TIFF image using the Pillow library.","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":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Pillow is a Python imaging library. Prior to 13.0.0, Pillow's TIFF encoder can read beyond a ColorMap buffer when retained TIFF metadata has a plane size inconsistent with BitsPerSample. A small TIFF can be opened normally and then retain a crafted ColorMap that is reused when the image is saved. An application that re-encodes the attacker's TIFF with libtiff can trigger the out-of-bounds read. This can disclose heap memory in the output or crash the process.
