WP Photo Album Plus <= 9.3.02.002 — Authenticated (Custom+) Command Injection via 'value' Parameter (crop item) in update-photo AJAX Action

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under WP Photo Album Plus.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 9.3.02.003, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch WP Photo Album Plus to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Wordfence PRISM.

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.
