{"id":"CVE-2026-114608","published":"2026-10-22T17:16:58.750","lastModified":"2026-10-22T17:40:46.877","description":"Pylint is a static code analyser for Python. From 0.15.2 until 4.0.9, Pylint stores module statistics in predictable files under PYLINT_HOME and loads those files with pickle.load on a later run. An attacker who can write to a shared, group-writable, or otherwise untrusted cache directory can replace a stats cache with crafted serialized data, causing arbitrary code to execute with the privileges of the user who next runs Pylint. The default per-user cache is not normally writable by another user. This issue is fixed in version 4.0.9.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://github.com/pylint-dev/pylint/commit/58c87cffca9de2b3e89aa07b89686cbc90cfea2d","tags":[]},{"url":"https://github.com/pylint-dev/pylint/commit/5b241f66318220e9ba7b21ca631fbfe8e77682ca","tags":[]},{"url":"https://github.com/pylint-dev/pylint/releases/tag/v4.0.9","tags":[]},{"url":"https://github.com/pylint-dev/pylint/security/advisories/GHSA-22qq-2fwx-7p67","tags":[]}],"exploitRefs":[{"url":"https://github.com/pylint-dev/pylint/commit/58c87cffca9de2b3e89aa07b89686cbc90cfea2d","tags":[]},{"url":"https://github.com/pylint-dev/pylint/commit/5b241f66318220e9ba7b21ca631fbfe8e77682ca","tags":[]},{"url":"https://github.com/pylint-dev/pylint/releases/tag/v4.0.9","tags":[]},{"url":"https://github.com/pylint-dev/pylint/security/advisories/GHSA-22qq-2fwx-7p67","tags":[]}],"hasPoc":true,"ai":null}
