The "HTML Include and replace macro" plugin before 1.5.0 for Confluence Server allows a bypass of the includeScripts=false XSS protection me
Noroxi assessment
Priority: Monitor (action score 27/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 1.3% (FIRST EPSS); higher than 70.1% of all records.
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
The "HTML Include and replace macro" plugin before 1.5.0 for Confluence Server allows a bypass of the includeScripts=false XSS protection mechanism via vectors involving an IFRAME element.
