{"id":"CVE-2025-27607","summary":"Python JSON Logger has a Potential RCE via missing `msgspec-python313-pre` dependency","details":"Python JSON Logger is a JSON Formatter for Python Logging. Between 30 December 2024 and 4 March 2025 Python JSON Logger was vulnerable to RCE through a missing dependency. This occurred because msgspec-python313-pre was deleted by the owner leaving the name open to being claimed by a third party. If the package was claimed, it would allow them RCE on any Python JSON Logger user who installed the development dependencies on Python 3.13 (e.g. pip install python-json-logger[dev]). This issue has been resolved with 3.3.0.","aliases":["GHSA-wmxh-pxcx-9w24"],"modified":"2025-12-05T08:53:52.889913Z","published":"2025-03-07T16:18:13.789Z","database_specific":{"cwe_ids":["CWE-829"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/27xxx/CVE-2025-27607.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/27xxx/CVE-2025-27607.json"},{"type":"FIX","url":"https://github.com/nhairs/python-json-logger/commit/2548e3a2e3cedf6bef3ee7c60c55b7c02d1af11a"},{"type":"FIX","url":"https://github.com/nhairs/python-json-logger/commit/e7761e56edb980cfab0165e32469d5fd017a5d72"},{"type":"ADVISORY","url":"https://github.com/nhairs/python-json-logger/security/advisories/GHSA-wmxh-pxcx-9w24"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-27607"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nhairs/python-json-logger","events":[{"introduced":"c6c804171381b7500823a8f151101a56f80853a8"},{"fixed":"9e6cb679dfb56cb82d9a8cc91f956efd72427055"}]}],"versions":["v3.2.0","v3.2.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-27607.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
