Halo's editor has a stored Cross-Site Scripting vulnerability

Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 0.35% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: halo-dev halo 2.17.0.

Low priority for now. Upgrade to halo-dev halo 2.17.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Halo is an open source website building tool. A security vulnerability has been identified in versions prior to 2.17.0 of the Halo project. This vulnerability allows an attacker to execute malicious scripts in the user's browser through specific HTML and JavaScript code, potentially leading to a Cross-Site Scripting (XSS) attack. Users are advised to upgrade to version 2.17.0+. There are no known workarounds for this vulnerability.
