Detailsinfo

A vulnerability has been found in davidanderson UpdraftPlus Plugin up to 1.26.4 on WordPress and classified as problematic. Affected by this vulnerability is the function UpdraftPlus_Remote_Communications_V2::wp_loaded. The manipulation with an unknown input leads to a signature verification vulnerability. The CWE definition for the vulnerability is CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.26.4 via the UpdraftPlus_Remote_Communications_V2::wp_loaded function. This is due to insufficient validation of the remote communications message format, where signature verification can be bypassed and unchecked decryption return values collapse to a predictable all-zero encryption key. This makes it possible for unauthenticated attackers to forge arbitrary RPC commands and run them as the connected administrator, such as uploading and activating a malicious plugin, which ultimately leads to remote code execution.

The weakness was published by Xu Wei Ting. The advisory is shared at wordfence.com. This vulnerability is known as CVE-2026-10795 since 06/03/2026. The exploitation appears to be difficult.
