  • Oct 13, 2026Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to persist unneutralized markup CVE-2026-63168 · Other software · Omnispace · reported by VulnCheckMedium 5.1

    Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to persist unneutralized markup by submitting malicious values as two-dimensional POST arrays through the LDAP/person import flow, bypassing the paramsFilter() request parameter filter which failed to recurse into nested arrays. Attackers can inject arbitrary script code into a user profile that is later rendered to other users, resulting in execution of malicious scripts in victims' browsers.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
