Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a WordPress site running the Tickera (Event Ticketing System) plugin at version 3.6.0.2 or earlier, with a network-reachable Tickera request handler that passes attacker input to PHP's unserialize(). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H describes a network-reachable, low-complexity, unauthenticated, no-interaction flaw with high impact across all three dimensions - a maximal-severity profile that, on paper, warrants urgent patching. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Tickera to the first release published after 3.6.0.2 that the vendor identifies as fixing this issue; no vendor-released patched version is independently confirmed in the available data, so verify the exact fix version against the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/tickera-event-ticketing-system/vulnerability/wordpress-tickera-plugin-3-6-0-2-php-object-injection-vulnerability) and the plugin changelog before deploying. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all WordPress installations using Tickera plugin and assess whether they are internet-exposed; if critical to operations, immediately disable the plugin or restrict access to internal/VPN networks only to prevent exploitation. …
