CVE-2026-5713
Published: April 15, 2026Last modified: August 19, 2026
Description
The "profiling.sampling" module (Python 3.15+) and "asyncio introspection capabilities" (3.14+, "python -m asyncio ps" and "python -m asyncio pstree") features could be used to read and write addresses in a privileged process if that process connected to a malicious or "infected" Python process via the remote debugging feature. This vulnerability requires persistently and repeatedly connecting to the process to be exploited, even after the connecting process crashes with high likelihood due to ASLR.
Notes
Only affects Python 3.14+ Fixed in Stream. 23 LTS (3.11) and 25 LTS (3.12) not affected.
