Tickera WordPress plugin: Blind SQL injection
Summary
The Tickera event ticketing plugin for WordPress up to and including version 3.6.0.6 is affected by blind SQL injection. An attacker can send crafted requests to read, modify or delete database content, including customer and order data. The CNA record states that no privileges are required, but this is not yet confirmed, and other Tickera SQL injection issues required Staff access. Scores differ between sources: CVSS 9.3 (CNA), 7.3 (VulDB) and 5.8 (one Rapid7/Vulners view).
Affected
- Tickera WordPress plugin (tickera-event-ticketing-system) up to and including 3.6.0.6
Fixed in
- Update to version 3.6.0.7 or later (version stated by Patchstack; verify against the vendor changelog).
- WordPress.org currently lists version 3.6.0.8.
Workaround
Unknown. No interim mitigation found; a patched version is available.
Exploitation
- Not known to be exploited in the wild; not listed in CISA KEV.
- CISA SSVC: exploitation none, automatable yes.
- VulDB reports no available exploit; no public proof of concept found.
- Patchstack rates it as high priority and expects exploitation.
- EPSS score: 0.00248.
Our recommendation
- Check whether the Tickera plugin is installed and which version is running.
- Update to the latest available version without delay.
- Check whether the site accepts unauthenticated requests to the affected code path; treat it as possibly unauthenticated until verified.
- Review web server and plugin logs for unusual requests and check whether customer data may have been accessed; assess data-protection obligations under the Swiss FADP if so.
