What is CVE-2026-27744?
CVE-2026-27744 is a critical code injection vulnerability in SPIP tickets, published on 25 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The SPIP tickets plugin versions prior to 4.3.3 contain an unauthenticated remote code execution vulnerability in the forum preview handling for public ticket pages. The plugin appends untrusted request parameters into HTML that is later rendered by a template using unfiltered environment rendering (#ENV**), which disables SPIP output filtering. As a result, an unauthenticated attacker can inject crafted content that is evaluated through SPIP's template processing chain, leading to execution of code in the context of the web server.
