Contest Gallery Upload Vote Photos Media Sell With Paypal Stripe
Monthly
Arbitrary file overwrite in the Contest Gallery WordPress plugin (Upload & Vote Photos, Media, Sell with PayPal & Stripe) affects all versions up to and including 32.0.1, where the 'baseUrlForFacebook' parameter is passed to a file-writing routine without adequate path validation. Exploitation requires at least a subscriber-level account on the target WordPress site, but then allows overwriting known files on the server, which can escalate to remote code execution when the overwritten path is a PHP file that the web server later executes. No public exploit code or CISA KEV listing was provided in the source data for this CVE, so active exploitation is unconfirmed at time of analysis.
Privilege escalation in the Contest Gallery WordPress plugin (versions ≤ 30.0.2) allows authenticated Contributor/Author-level users to overwrite the stored RegistryUserRole option to 'administrator', causing newly registered Google sign-in accounts to be promoted to Administrator. The flaw was disclosed by Wordfence and stems from a missing capability check in the option-saving handler; no public exploit identified at time of analysis.
SQL injection in the Contest Gallery WordPress plugin (versions through 28.1.6) allows unauthenticated remote attackers to extract sensitive database contents by abusing the 'form_input' parameter handled by the 'post_cg_gallery_form_upload' AJAX action. The endpoint is gated only by a public nonce that is exposed in the page source of any public gallery page, effectively offering no protection against external attackers. No public exploit identified at time of analysis, but the issue was disclosed by Wordfence and affects a publicly reachable PHP endpoint.
The Contest Gallery plugin for WordPress contains an authentication bypass vulnerability that allows unaattacked attackers to take over administrator accounts and gain complete site control. All versions up to and including 28.1.5 are affected when the non-default RegMailOptional=1 setting is enabled. The vulnerability exploits MySQL type coercion by registering with specially crafted email addresses to overwrite admin activation keys, then using an unauthenticated login endpoint to authenticate as the target user. With a CVSS score of 8.1 and high attack complexity (AC:H), this represents a critical risk for sites using the vulnerable configuration.
Second-order SQL injection in the Contest Gallery WordPress plugin (all versions through 30.0.7) allows authenticated attackers with author-level access to append arbitrary SQL into backend queries via the `cgRealId` parameter within the `cg_multiple_files_for_post` upload mechanism. The injected payload is first stored in the database without adequate sanitization and later executed unsafely by backend AJAX handlers in `ajax/ajax-functions-backend.php` and gallery administration scripts, enabling extraction of sensitive information from the WordPress database. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
