CVE-2024-10263 describes an arbitrary shortcode execution vulnerability discovered in the Tickera – WordPress Event Ticketing plugin. This flaw allows unauthenticated attackers to execute arbitrary shortcodes, potentially leading to website defacement, data theft, or even complete system compromise. The vulnerability affects versions of Tickera up to and including 3.5.4.4. A patch is available, and users are strongly advised to upgrade immediately.
The impact of this vulnerability is significant due to its ease of exploitation and the potential for widespread damage. An attacker can leverage this flaw to inject malicious shortcodes into the WordPress site, which can then be executed by the server. This could lead to the execution of arbitrary PHP code, allowing the attacker to gain control of the website and its underlying system. Data stored within the Tickera plugin, such as event details, user information, and payment data, could be compromised. The attacker could also use this access to pivot to other systems on the same network, expanding the blast radius of the attack.
This vulnerability was publicly disclosed on 2024-11-05. No public proof-of-concept (PoC) code has been widely released, but the ease of exploitation suggests that it is likely to be targeted by attackers. The vulnerability is not currently listed on the CISA KEV catalog. Monitor security advisories and threat intelligence feeds for any signs of active exploitation.
