What is the CVSS score of CVE-2025-69872?

CVE-2025-69872 has a CVSS 3.1 base score of 9.8 (Critical). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. EPSS exploitation probability: 0.1%.

Which versions of Python are affected by CVE-2025-69872?

DiskCache library versions up to 5.6.3 contain a critical vulnerability allowing arbitrary code execution if an attacker gains write access to the cache directory.. A patch is available.

How to fix or mitigate CVE-2025-69872?

Within 24 hours: Identify all applications using python-diskcache and assess cache directory permissions and access controls. Within 7 days: Implement compensating controls including strict file system permissions (cache directory readable/writable by application user only), disable pickle serialization if alternative serialization options exist, or isolate affected services. Within 30 days: Monitor for vendor patch release and prepare upgrade testing; consider migrating to alternative caching solutions if patch timeline is unacceptable.

DescriptionCVE.org

DiskCache (python-diskcache) through 5.6.3 uses Python pickle for serialization by default. An attacker with write access to the cache directory can achieve arbitrary code execution when a victim application reads from the cache.

AnalysisAI

Unsafe deserialization in DiskCache Python library through 5.6.3. Uses pickle by default, allowing attackers with cache directory write access to execute arbitrary code.
