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-2026-112897 exists.\n\nAffected packages and fixed versions:\n- pillow (Bitnami): affected from 5.3.0; fixed in 13.0.0\n- pillow (PyPI): affected from 5.3.0; fixed in 13.0.0\n- Pillow (PyPI): affected from 5.3.0; 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-2026-112897/ (Markdown: https://insights.sbomify.com/CVE-2026-112897/index.md)","id":"CVE-2026-112897","markdown":"https://insights.sbomify.com/CVE-2026-112897/index.md","name":"CVE-2026-112897","record":{"aliases":["BIT-pillow-2026-112897","DEBIAN-CVE-2026-112897","ECHO-1c7d-7349-3e56","GHSA-q45j-58j2-45rg","ROOT-APP-PYPI-CVE-2026-112897","UBUNTU-CVE-2026-112897"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Python imaging library","requires_auth":"none","summary":"Attackers can disclose stale heap memory by supplying crafted TIFF images to applications 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":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"Pillow is a Python imaging library. From 5.3.0 until 13.0.0, Pillow can return uninitialized memory as pixels when libtiff performs a short decode of JPEG-compressed or Group 4 fax TIFF data. The _decodeStrip and _decodeTile buffers can be larger than the bytes written by libtiff, but Pillow converts the expected rows without clearing the unwritten tail. The tile path is affected from 5.3.0 and the strip path from 6.0.0. An attacker can supply a crafted TIFF to an application that loads and returns or re-encodes its pixels. This can disclose stale heap contents without memory corruption or a process crash.
