CVE-2025-4516 WRITEUP MEDIUM WRITEUP
CPython - Info Disclosure
There is an issue in CPython when using `bytes.decode("unicode_escape", error="ignore|replace")`. If you are not using the "unicode_escape" encoding or an error handler your usage is not affected. To work-around this issue you may stop using the error= handler and instead wrap the bytes.decode() call in a try-except catching the DecodeError.
CVE-2025-6069 WRITEUP MEDIUM WRITEUP
CPython < 3.9.24, 3.10.0-3.10.18, 3.11.0-3.11.13, 3.12.0-3.12.11, 3.13.0-3.13.5, 3.14.0a1-3.14.0b2 - DoS via HTML Parser

CVSS 5.5
CVE-2025-8291 WRITEUP MEDIUM WRITEUP
CPython <3.9.24, 3.10.0-3.10.18, 3.11.0-3.11.13, 3.12.0-3.12.11, 3.13.0-3.13.9, 3.14.0 - ZIP64 EOCD Validation Bypass
The 'zipfile' module would not check the validity of the ZIP64 End of Central Directory (EOCD) Locator record offset value would not be used to locate the ZIP64 EOCD record, instead the ZIP64 EOCD record would be assumed to be the previous record in the ZIP archive. This could be abused to create ZIP archives that are handled differently by the 'zipfile' module compared to other ZIP implementations. Remediation maintains this behavior, but checks that the offset specified in the ZIP64 EOCD Locator record matches the expected value.
