high Tenable Cloud Security Plugin ID 443506

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - phpBB before 3.3.16 is vulnerable to Host Header Injection that can lead to password rest link poisoning.
 When force_server_vars is disabled, the servers hostname may be extracted from the HTTP Host header which
 is used to generate the password reset link URL. An attacker who can manipulate the Host header (e.g.
 through misconfigured host setup or missing header validation by the webserver) can cause password reset
 emails to contain a link pointing to an attacker-controlled domain, potentially leading to account
 takeover. (CVE-2026-29199)

Solution

Update the phpbb/phpbb library and its related packages to version 3.3.16 or later.
