CVE-2026-1261709.8 CRÍ—
——0A improper encoding or escaping of output vulnerability in Fortinet FortiAnalyzer 8.0.0 through 8.0.2, FortiAnalyzer 7.6.0 through 7.6.7, FortiAnalyzer Cloud 8.0.1 through 8.0.2, FortiAnalyzer Cloud 7.6.0 through 7.6.7, FortiAnalyzer-BigData 7.6.0 through 7.6.2, FortiManager 8.0.0 through 8.0.2, FortiManager 7.6.0 through 7.6.7, FortiManager Cloud 8.0.1 through 8.0.2, FortiManager Cloud 7.6.0 through 7.6.7 may allow an unauthenticated attacker to execute unauthorized code or commands via a specially crafted HTTP request21hCVE-2026-646717.2 ALT12.8%
——4Waline is a comment system with backend support. In versions 3.15.2 and prior, the @waline/client UserList widget builds its DOM by concatenating server-returned commenter fields directly into root.innerHTML with no HTML escaping. The commenter nick and link are stored and returned verbatim by the server (only the comment body is sanitized), and the link field is never sent to the spam filter. So an unauthenticated visitor who posts a comment with link = x"><img src=x onerror=...> achieves stored cross-site scripting that executes, with no interaction, in the browser of every visitor to a page that embeds the UserList widget. At time of publication, there are no publicly available patches.2dCVE-2026-646709.3 CRÍ30.1%
——9Waline is a comment system with backend support. In versions 3.15.2 and prior, @waline/client renders the comment editor's live preview with marked and no sanitizer (utils/markdown.ts), and the preview is injected with v-html. When a comment is edited, the editor is seeded with the comment's raw, un-sanitized body (orig). Only administrators and the comment owner can edit. So an administrator who clicks Edit on an attacker's comment renders that attacker's raw HTML in their own session: an unauthenticated commenter achieves privilege-escalation stored XSS against a moderator with a single Edit click. At time of publication, there are no publicly available patches.2dCVE-2026-92558—38.6%
——12The proxy-cache and proxy-cache-advanced plugins in Kong Gateway Enterprise and Kong AI Gateway do not escape separator characters when building the cache key, allowing a remote attacker to cause a response cached for one request to be served for a different request on the same Route.2dCVE-2026-126063—47.1%
——14Nokogiri is an open source XML and HTML library for the Ruby programming language. From 1.12.0 until 1.19.5, the C extension on CRuby and TruffleRuby has a Nokogiri::HTML5 serializer that does not escape text inside noscript elements or angle brackets inside attribute values. When an application sanitizes untrusted HTML with the default parsing options, allows noscript, and sends serialized output to a scripting-enabled browser, the browser can parse markup that Nokogiri did not produce, enabling mutation cross-site scripting. Using parse_noscript_content_as_text: true is the recommended workaround, not the vulnerable default. JRuby is not affected because it does not implement Nokogiri::HTML5. This issue is fixed in version 1.19.5.2dCVE-2026-1094766.1 MED51.0%
