An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-112401 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pillow (Bitnami): affected from 5.4.0; fixed in 13.0.0\n- pillow (PyPI): affected from 5.4.0; fixed in 13.0.0\n- Pillow (PyPI): affected from 5.4.0; 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-2026-112401/ (Markdown: https://insights.sbomify.com/CVE-2026-112401/index.md)","id":"CVE-2026-112401","markdown":"https://insights.sbomify.com/CVE-2026-112401/index.md","name":"CVE-2026-112401","record":{"aliases":["BIT-pillow-2026-112401","DEBIAN-CVE-2026-112401","ECHO-c6b8-6481-18c0","GHSA-74r2-7ff9-mjj2","UBUNTU-CVE-2026-112401"],"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":"Attackers can cause excessive CPU consumption and denial of service by submitting crafted GIF files to applications using the Pillow library.","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":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/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 5.4.0 until 13.0.0, Pillow performs quadratic copying while parsing GIF comments. GifImageFile._seek() repeatedly appends immutable bytes for comment sub-blocks and multiple comment extensions, and frame zero is parsed during Image.open(). An attacker can submit a small-dimension GIF containing many comment extensions to any application that opens the file. This can consume excessive CPU and deny service before the application can inspect the image.
