Security readout for executives and security teams
Plain-English summary
A critical SQL injection flaw allows an unauthenticated internet user to target vulnerable Joomla sites running iCagenda versions 4.0.0 through 4.0.11. Successful exploitation could expose database information, alter data, disrupt service, and affect connected systems. The supplied sources do not confirm active exploitation or provide a specific fixed release.
Executive priority
Treat this as an urgent inventory and containment issue for public-facing Joomla sites. Prioritize identifying affected iCagenda installations immediately, restrict exposure where feasible, and follow authoritative vendor guidance. Escalate any suspicious unauthenticated com_ajax activity for incident review. Current evidence supports critical technical risk but does not establish active exploitation.
Technical view
CVE-2026-67365 is CWE-89 in the iCagenda mod_icagenda_calendar Joomla module. The vulnerable path is reachable through com_ajax without a session, token, account, or user interaction. CVSS 4.0 rates it 9.2 with network access, low complexity, and additional attack requirements. Database confidentiality impact is high; integrity and availability impacts are rated low.
Likely exposure
Exposure is highest for internet-accessible Joomla installations using iCagenda versions 4.0.0 through 4.0.11 where the affected com_ajax functionality is reachable. The bundle states other versions are unaffected by default, but provides no deployment-specific detection criteria. Internal or access-restricted sites have lower reachability, not necessarily lower technical impact.
Exploitation context
The flaw is remotely reachable and requires no authentication or user interaction, substantially reducing attacker prerequisites. The CVSS vector records additional attack requirements, but the sources do not explain them. This CVE is not identified as KEV in the supplied bundle, and no cited source confirms exploitation in the wild or public exploit availability.
Researcher notes
The affected-version notation is interpreted from the bundle as versions 4.0.0 through 4.0.11. No specific vulnerable parameter, root cause details, patch identifier, fixed release, indicators of compromise, or exploitation evidence are supplied. Researchers should avoid inferring those details and monitor the CVE record, CVE List V5 entry, and vendor site for updates.
Mitigation direction
- Inventory Joomla sites and identify installations running iCagenda versions 4.0.0 through 4.0.11.
- Check current iCagenda and CVE guidance for an approved fixed release or vendor mitigation.
- If operationally acceptable, disable the affected module until authoritative remediation guidance is available.
- Restrict unnecessary public access to affected functionality using existing application or edge controls.
- Preserve relevant web and application logs for investigation.
Validation and detection
- Confirm the installed iCagenda version on every Joomla deployment.
- Verify whether the affected com_ajax functionality is reachable from untrusted networks.
- Review logs for unusual or repeated unauthenticated requests involving com_ajax and the calendar module.
- After remediation, confirm the vulnerable version is absent and intended calendar functionality still works.
- Recheck authoritative CVE and vendor sources for clarified affected versions and remediation details.

Improper Neutralization of Special Elements used in an SQL Command
Improper Neutralization of Special Elements used in an SQL Command represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
