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-2026-114501/ (Markdown: https://insights.sbomify.com/CVE-2026-114501/index.md)","id":"CVE-2026-114501","markdown":"https://insights.sbomify.com/CVE-2026-114501/index.md","name":"CVE-2026-114501","record":{"aliases":["BIT-pillow-2026-114501","CLSA-2026-1793101237","DEBIAN-CVE-2026-114501","ECHO-260c-4537-5719","GHSA-654x-cwwv-5j9c","PYSEC-2026-4336","UBUNTU-CVE-2026-114501"],"analysis":null,"analysis_generated_by":null,"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:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"},{"id":"CWE-226","name":"Sensitive Information in Resource Not Removed Before Reuse"}],"description":"Pillow is a Python imaging library. From 11.2.1 until 13.0.0, Arrow export assumes that an image's rows are tightly contiguous and exports from im-\u003eblocks[0].ptr even when PILLOW_ALIGNMENT makes aligned_linesize include row padding or an aligned offset before the first row. The resulting Arrow buffer can include uninitialized padding, bytes preceding the first row, or stale heap contents from previously freed images. Applications that configure alignment and export images to Arrow can therefore disclose one user's pixels or other process memory to another user.
