CVE-2025-15366 Details
Description
The imaplib module, when passed a user-controlled command, can have additional commands injected using newlines. Mitigation rejects commands containing control characters.
A command injection vulnerability has been identified in the Python imaplib module. When a user-controlled command is sent, additional commands can be injected by including newlines. This issue arises because the module does not properly sanitize input before processing it, allowing for the manipulation of IMAP commands. The vulnerability affects the standard library imaplib module in CPython.
The vulnerability has been addressed by updating the imaplib module to reject commands containing control characters. Users should ensure they are using a version of Python that includes this fix.
