Other vulnerabilities in Contest Gallery
See all- CVE-2026-40771Critical
There is an unauthenticated SQL Injection vulnerability in Contest Gallery versions up to 28.1.6.
- CVE-2026-107120Medium
The Contest Gallery WordPress plugin before 33.0.1 does not limit the number of attempts against its front-end registration email-verification step, which relies on a short numeric PIN, allowing unauthenticated attackers to brute-force the PIN and create and activate a WordPress account bound to an email address they do not own, gaining an authenticated session.
- CVE-2026-61986High
Unauthenticated Cross Site Scripting (XSS) vulnerability in Contest Gallery plugin versions up to 30.0.5. An attacker can inject malicious script without authentication.
- CVE-2026-16586Medium
The Contest Gallery plugin for WordPress up to version 30.0.7 is vulnerable to second-order SQL injection via the cg_multiple_files_for_post and cgRealId parameters. Insufficient escaping and lack of query preparation allow authenticated attackers with author-level access to append additional SQL queries, potentially extracting sensitive information.
- CVE-2026-16055High
The Contest Gallery WordPress plugin before 30.0.7 does not route its front-end login through the standard WordPress authentication flow, issuing an authentication cookie directly after the password check, which bypasses installed brute-force-protection and two-factor-authentication. This enables unlimited, unthrottled password guessing against any account (including administrators) up to full account takeover.
- CVE-2026-16057Medium
The Contest Gallery WordPress plugin before version 30.0.7 fails to perform capability or nonce checks in one of its post-deletion handlers, relying only on a coarse role-membership test. This allows any Author-level or higher user to permanently delete arbitrary posts, pages, and other content they do not own.
- CVE-2026-65447High
A Cross Site Scripting (XSS) vulnerability in the Contest Gallery plugin for WordPress versions up to 30.0.6. An unauthenticated attacker can inject a malicious script.

Original NVD description (English source)
The Contest Gallery – Upload, Vote & Sell with PayPal and Stripe plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple form field parameters in all versions up to, and including, 27.0.2. This is due to insufficient input sanitization and output escaping on user-supplied attributes. This makes it possible for authenticated attackers, with author-level access or higher, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
