The manipulation of the argument queue name leads to cross site scripting. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The identifier of the patch is 542aa8449b5aa889b3a54f419e794afe19f56d5d/0ce7b4f1193c0ed6c6e31a960fafededf979eef2. It is recommended to apply a patch to fix this issue. | |
| CVE-2026-27954 | 0.00 | — | 0.00 | Feb 26, 2026 | Live Helper Chat is an open-source application that enables live support websites. In versions up to and including 4.52, three chat action endpoints (holdaction.php, blockuser.php, and transferchat.php) load chat objects by ID without calling `erLhcoreClassChat::hasAccessToRead()`, allowing operators to act on chats in departments they are not assigned to. Operators with the relevant role permissions (holduse, allowblockusers, allowtransfer) can hold, block users from, or transfer chats in departments they are not assigned to. This is a horizontal privilege escalation within one organization. As of time of publication, no known patched versions are available. |
