DescriptionCVE.org

The WP Photo Album Plus WordPress plugin before 9.2.09.002 does not check that the current user is allowed to upload into the album they target when it processes a front-end upload, allowing any authenticated user, such as a Subscriber, to upload files into albums owned by other users or by the administrator. Exploitation requires the WP Photo Album Plus WordPress plugin before 9.2.09.002's front-end user upload feature to be enabled, which is not the default.

AnalysisAI

Insufficient authorization in WP Photo Album Plus (all versions before 9.2.09.002) allows any authenticated WordPress user-including low-privilege Subscriber accounts-to upload files into photo albums owned by other users or administrators. The flaw is rooted in CWE-639 (Authorization Bypass Through User-Controlled Key): the plugin's front-end upload endpoint accepts a caller-supplied album identifier without verifying ownership, enabling cross-user content injection. A publicly available POC exists via WPScan; no active exploitation is confirmed in CISA KEV, and the attack surface is constrained by a non-default configuration prerequisite.

Technical ContextAI

WP Photo Album Plus is a WordPress plugin providing gallery, album, and front-end upload management. The vulnerable code path is the front-end upload handler, which processes file submissions that include a user-supplied album ID as the upload target. CWE-639 (Authorization Bypass Through User-Controlled Key) precisely describes the root cause: the application trusts a client-provided reference-the album ID-without verifying that the authenticated user has ownership or write permission for that resource. Because WordPress's role system grants Subscriber accounts minimal permissions, the plugin's failure to enforce album-level authorization creates a horizontal (and upward) privilege escalation for file placement. CPE data (cpe:2.3:a:unknown:wp_photo_album_plus:*:*:*:*:*:*:*:*) confirms the affected artifact is a WordPress plugin; the 'unknown' vendor field reflects an unresolved NVD mapping rather than true vendor ambiguity. All releases from 0 through 9.2.09.001 carry this flaw.

RemediationAI

Update WP Photo Album Plus to version 9.2.09.002 or later, which is the confirmed patched release per the WPScan advisory (https://wpscan.com/vulnerability/146079f7-d4e5-4f1e-a715-f681fc33ed6a/) and ENISA EUVD-2026-57104. As an immediate compensating control requiring no downtime, disable the plugin's front-end user upload feature in its settings panel-this entirely eliminates the vulnerable code path and carries no operational trade-off for sites that do not rely on visitor-facing uploads. If front-end uploads are operationally required before patching, restrict WordPress user registration to trusted roles only to prevent untrusted Subscriber accounts from being leveraged; note that this mitigation is incomplete if existing untrusted subscriber accounts are already present on the site.
