GHSA-8MPJ-M6QM-5QR8 Mistune directives/include: mutual `.. include::` recursion crashes the renderer with `RecursionError`, denial of service via two attacker-controlled markdown files

Summary Type: Uncontrolled recursion via mutual include. The Include directive checks for direct self-reference a.md cannot include a.md, but does not detect indirect cycles. Two markdown files that include each other a.md → includes b.md → includes a.md cause unbounded recursion until Python's...

BIT-NGINX-2026-42533 NGINX Map directive and Regex matching vulnerability

A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and a string expression references the map's regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable i...

BIT-NGINX-AGENT-2026-60062 NGINX Agent Vulnerability

The NGINX Agent configdirs directive allows a low-privileged attacker to gain limited read and write access to files outside of the designated secure directory. The configdirs directive required for this issue can also be configured through NGINX Instance Manager. A successful exploit may allow a...

NGINX Map directive and Regex matching vulnerability

...

CVE-2026-42533

A flaw was found in NGINX. An unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP requests when the map directive uses regular expression regex matching and references regex capture variables before referencing the map output variable. This can lead to a heap...
