CVE-2026-44504Public exploitNetwork attack vector

State disclosure and injection via unchecked thread ID

Published May 14, 2026 · Updated May 14, 2026

Improper authorization in Aegra before 0.9.7 allows remote authenticated users to read and alter another tenant's thread state. The three thread-scoped run creation endpoints pass a caller-supplied thread_id to _prepare_run without filtering the thread by the authenticated identity, while an absent custom policy handler defaults to allow. Exploitation requires a shared multi-user instance and another tenant's leaked UUID, and it exposes checkpoint output and persists attacker-supplied conversation messages.
