CVE-2026-92115

8.8High

Published 16 Oct 2026 · NVD status: Deferred · AI triage by gemini-3.8-flash

8.8High

Attack vector: Network
Complexity: Low
Privileges needed: Low
User interaction: None
Impact: Full C/I/A compromise
Weakness: CWE-77

Impact

Authenticated users with the plugin's wppa_upload capability can execute arbitrary shell commands as the web-server user. Exploitation requires network access, an account with wppa_upload permissions, and ImageMagick enabled on the server.

Root cause

The wppa_image_magick_a() function directly concatenates the user-supplied value parameter into an exec() call without shell escaping, while wppa_decode() reconstructs shell metacharacters.

Affected systems

WP Photo Album Plus up to and including 9.3.02.002

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Fix & remediation

Upgrade WP Photo Album Plus to version 9.3.02.003 or later. If patching immediately is not possible, revoke the wppa_upload capability from untrusted roles in the plugin's settings or disable ImageMagick support.

shell

$ wp plugin update wp-photo-album-plus --version=9.3.02.003

NVD description

The WP Photo Album Plus plugin for WordPress is vulnerable to authenticated Command Injection in all versions up to, and including, 9.3.02.002 via the `value` parameter of the `update-photo` AJAX action. This is due to insufficient shell escaping within the `wppa_image_magick_a()` function, where the attacker-controlled `value` parameter is concatenated raw — without `escapeshellarg()` — into an ImageMagick command string before being passed to `exec()`; further, `wppa_decode()` actively restores percent-encoded shell metacharacters (e.g., `%26`→`&`, `%23`→`#`) rather than stripping them, allowing crafted payloads to survive sanitization and break out of the ImageMagick argument context. This makes it possible for authenticated attackers holding the plugin-defined `wppa_upload` capability to execute arbitrary operating-system commands as the web-server user, achieving full remote code execution on the underlying server. Exploitation requires ImageMagick to be enabled on the server; the `wppa_upload` capability is a plugin-level privilege that site administrators may grant to lower-privileged WordPress roles via the plugin's Users settings, broadening the pool of potential attackers beyond administrators.
