What is CVE-2026-49954?
CVE-2026-49954 is a high-severity path traversal vulnerability in Discuz! X5.0, published on 15 Jun 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
Discuz! X5.0 releases 20260320 through 20260610 contain a local file inclusion vulnerability that allows authenticated administrators to execute arbitrary code by importing a specially crafted plugin configuration containing path traversal sequences in the directory attribute. Attackers can trigger an exception during plugin installation to bypass sanitization routines, causing malicious paths to be stored unsanitized and subsequently passed to include(), which combined with file upload functionality escalates to arbitrary code execution in the context of the web server user.
Weakness: CWE-98
