In affected versions of Octopus Server the help sidebar can be customized to include a Cross-Site Scripting payload in the support link.

Noroxi assessment

Priority: Monitor (action score 21/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.38% (FIRST EPSS).
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.

Primary sources: NVD · CVE.org · FIRST EPSS

In affected versions of Octopus Server the help sidebar can be customized to include a Cross-Site Scripting payload in the support link. This was initially resolved in advisory 2022-07 however it was identified that the fix could be bypassed in certain circumstances. A different approach was taken to prevent the possibility of the support link being susceptible to XSS
