Is WP Photo Album Plus safe? Known vulnerabilities and latest version

The WP Photo Album Plus WordPress plugin before 9.3.04.004 does not verify the origin or a security token for one of its comment-management requests, allowing attackers to delete photo comments by tricking a logged-in user who holds comment-moderation rights into loading a crafted page.

The WP Photo Album Plus WordPress plugin before 9.2.11.002 does not properly escape a category navigation value before reflecting it into a JavaScript event handler on its gallery breadcrumb links, allowing unauthenticated attackers to inject arbitrary script that executes in the browser of anyone who follows a crafted gallery link and clicks the breadcrumb, including a logged-in administrator.

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.

The WP Photo Album Plus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REQUEST_URI Session History in all versions up to, and including, 9.3.03.002 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The bypass works because esc_url_raw() strips literal angle brackets but retains HTML entities, which wppaEntityDecode() silently converts back to live HTML tags before jQuery('#wppa-modal-container').html() renders them.

Subscriber Cross Site Scripting (XSS) in WP Photo Album Plus <= 9.3.02.003 versions.

Unauthenticated Cross Site Scripting (XSS) in WP Photo Album Plus <= 9.3.02.002 versions.

The WP Photo Album Plus plugin for WordPress is vulnerable to Remote Code Execution in all versions via the wppa_image_magick function. This is due to insufficient sanitization of the multipart upload filename before concatenation into an ImageMagick command string executed via exec(), with only escapeshellcmd() applied to the whole command rather than quoting individual arguments. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute code on the server. escapeshellcmd() escapes shell metacharacters but does not prevent argument injection because spaces remain as argument separators, and the filename sanitization applied at the database layer is never applied to the physical temporary file path used for ImageMagick processing.

The WP Photo Album Plus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'HTTP_X_FORWARDED_FOR' parameter in all versions up to, and including, 9.2.08.003 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The nonce failure path for the getshortcodedrenderedfenodelay action serves as the log-write trigger rather than an access barrier — a deliberately failed nonce check causes wppa_log() to record the attacker-supplied X-Forwarded-For value to disk, making the exploit fully reachable by unauthenticated callers via the wp_ajax_nopriv_wppa endpoint.

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.

The WP Photo Album Plus WordPress plugin before 9.2.07.002 does not perform any capability or nonce check on one of its public endpoint actions and builds an option name from a client-supplied value without restricting it to its own options, allowing unauthenticated users to read the value of other autoloaded options whose names end in a matching suffix.

The WP Photo Album Plus WordPress plugin before 9.2.07.002 does not validate a client-controlled value used to build a file path in one of its public endpoint actions, and performs no authorisation check on it, allowing unauthenticated attackers to delete arbitrary ZIP archives on the server, including ones stored outside the web root.

The WP Photo Album Plus WordPress plugin before 9.2.07.002 does not sanitise and escape a parameter before reflecting it into an inline script block, which could allow unauthenticated attackers to perform Reflected Cross-Site Scripting attacks against anyone who is tricked into opening a crafted link to a page displaying one of its galleries.

The WP Photo Album Plus WordPress plugin before 9.2.07.002 does not perform any capability or nonce check on one of its public REST endpoint actions, allowing unauthenticated users to delete the generated album export ZIP archives it stores.

WP Photo Album Plus is vulnerable to stored Cross-Site Scripting in all versions up to, and including, 9.2.03.001 through a decode-after-sanitize (double-encoding) flaw in the photo-comment pipeline. On write, `wppa_do_comment()` sanitizes the comment with `wppa_filter_html()` (wp_kses) followed by `wp_strip_all_tags()` (`wppa-functions.php:2623-2624`). Because `wp_strip_all_tags()` only removes *real* tags, an attacker who submits a **double HTML-entity-encoded** payload (e.g. `&amp;lt;img src=... onload=...&amp;gt;`) passes the write filters as harmless entity text and is stored one decode-level down (`&lt;img ... onload=...&gt;`).

The WP Photo Album Plus plugin for WordPress is vulnerable to generic SQL Injection via the 'table' parameter in all versions up to, and including, 9.2.04.002 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The export-table endpoint lacks a nonce check, meaning this vulnerability can also be triggered via CSRF by tricking an authenticated administrator into visiting a malicious page.

Unauthenticated Cross Site Scripting (XSS) in WP Photo Album Plus <= 9.2.02.004 versions.

The WP Photo Album Plus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'subtext' parameter in all versions up to, and including, 9.1.13.005 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. A contributor-level attacker can embed the malicious [photo] shortcode in a post submitted for review, causing the stored payload to execute when an administrator or any other user views the post.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Jacob N. Breetvelt WP Photo Album Plus allows Blind SQL Injection. This issue affects WP Photo Album Plus: from n/a through 9.1.13.005.

Unauthenticated SQL Injection in WP Photo Album Plus <= 9.1.08.001 versions.

The WP Photo Album Plus WordPress plugin before 9.1.11.001 does not properly sanitize and escape a parameter before using it in a SQL query, allowing unauthenticated users to perform SQL injection attacks.

The WP Photo Album Plus plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘shortcode’ parameter in all versions up to, and including, 9.1.05.008 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The WP Photo Album Plus plugin for WordPress is vulnerable to Cross-Site Scripting in all versions up to, and including, 9.0.11.006 due to insufficient input sanitization and output escaping in the wppa_user_upload function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in the photo album descriptions that execute in a victim's browser.

The The WP Photo Album Plus plugin for WordPress is vulnerable to arbitrary shortcode execution via getshortcodedrenderedfenodelay AJAX action in all versions up to, and including, 8.8.08.007 . This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

The WP Photo Album Plus plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'wppa-tab' parameter in all versions up to, and including, 8.8.05.003 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
