WP Photo Album Plus WordPress plugin vulnerabilities

The WP Photo Album Plus WordPress plugin before version 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 WordPress plugin before version 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.

The WP Photo Album Plus plugin up to version 9.2.03.001 is vulnerable to stored Cross-Site Scripting (XSS) due to a double-encoding flaw in the photo comment pipeline. An attacker can submit a double HTML-entity-encoded payload (e.g., <img src=... onload=...>) that passes filters and is stored, then executes in the victim's browser.
