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-2026-112894 exists.\n\nAffected packages and fixed versions:\n- pillow (Bitnami): affected from 5.1.0; fixed in 13.0.0\n- pillow (PyPI): affected from 5.1.0; fixed in 13.0.0\n- Pillow (PyPI): affected from 5.1.0; 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-2026-112894/ (Markdown: https://insights.sbomify.com/CVE-2026-112894/index.md)","id":"CVE-2026-112894","markdown":"https://insights.sbomify.com/CVE-2026-112894/index.md","name":"CVE-2026-112894","record":{"aliases":["BIT-pillow-2026-112894","DEBIAN-CVE-2026-112894","ECHO-54bd-4ebb-6978","GHSA-jg86-v3jv-hrpm","ROOT-APP-PYPI-CVE-2026-112894","UBUNTU-CVE-2026-112894"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python imaging library","requires_auth":"none","summary":"An attacker can cause excessive CPU consumption and denial of service by supplying a crafted multi-frame image to applications using Pillow for PDF conversion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-407","name":"Inefficient Algorithmic Complexity"}],"description":"Pillow is a Python imaging library. From 5.1.0 until 13.0.0, Pillow takes quadratic time to reserve PDF object identifiers when saving many frames with save_all enabled. PdfParser.next_object_id() repeatedly rebuilds and scans all previously reserved identifiers for every object. An attacker can supply a multi-frame image, including a small APNG with a large declared frame count, to an application that converts it to a multipage PDF. This can consume excessive CPU and deny service.
