Summary
CVE-2026-54829 is a Blind SQL Injection vulnerability (CWE-89) in the WP Photo Album Plus WordPress plugin by Jacob N. Breetvelt, affecting all versions through 9.1.13.005. The vulnerability is remotely exploitable without authentication or user interaction and carries a CVSS v3.1 score of 7.5 (High) with a changed scope and high confidentiality impact. The plugin has over 10,000 active installations, making its internet-exposed attack surface considerable.
Technical details
- Root cause: Improper neutralization of special elements used in SQL commands — user-supplied input is not adequately sanitized or parameterized before being incorporated into database queries, enabling injection of arbitrary SQL statements.
- Trigger conditions: The flaw is exploitable under conditions of high attack complexity (AC:H), meaning specific non-default configuration states must be present; however, no authentication or user interaction is required once those conditions are met.
- Attack vector: Network-accessible; an unauthenticated remote attacker can send crafted HTTP requests to the affected WordPress installation to manipulate backend database queries via Blind SQL Injection.
- Impact: Successful exploitation allows an attacker to extract sensitive data from the underlying WordPress database — including user credentials, session tokens, personal data, and application secrets. The changed scope (S:C) indicates the impact extends beyond the plugin itself to the broader WordPress environment. Availability is also partially affected (A:L).
Affected software
- WP Photo Album Plus (WordPress plugin) — all versions through 9.1.13.005
Severity
- CVSS v3.1 Base Score: 7.5 (High)
- Vector String:
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:L
Mitigation and recommended actions
- Immediate: Update WP Photo Album Plus to version 9.2.01.001 or later. The current release available via the WordPress Plugin Directory is 9.2.02.004 (updated June 19, 2026).
- Administrators unable to update immediately should consider temporarily disabling the plugin and restricting access to WordPress installations exposed to the internet until the patch can be applied.
- Review database access logs for anomalous or time-delayed query patterns indicative of blind SQL injection probing.
