CVE-2025-1734

Publication date 14 March 2025

Last updated 18 July 2025

Ubuntu priority

Medium

Why this priority?

In PHP from 8.1.* before 8.1.32, from 8.2.* before 8.2.28, from 8.3.* before 8.3.19, from 8.4.* before 8.4.5, when receiving headers from HTTP server, the headers missing a colon (:) are treated as valid headers even though they are not. This may confuse applications into accepting invalid headers.
