Summary
The Contest Gallery plugin for WordPress is vulnerable to CSV Injection in versions up to and including 27.0.3. Unauthenticated attackers can embed untrusted input into exported CSV files, potentially leading to code execution when these files are opened on a vulnerable local system.
Risk Assessment
The risk involves potential remote code execution on a user's machine when opening a malicious CSV file, which could lead to system compromise or data theft.
Recommendation
It is recommended to immediately update the Contest Gallery plugin to the latest patched version. Additionally, users should be warned about the risks of opening CSV files from untrusted sources.
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.
- CVE-2026-42660Medium
Contest Gallery versions up to 28.1.7 have a vulnerability that allows for the exposure of subscriber sensitive data.
- CVE-2026-42657Medium
