Advisory Released Date: 2025-06-23
Advisory Updated Date: 2025-06-23
Severity:
Medium
Issue Overview:
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-2025-4516)
