{"id":"DEBIAN-CVE-2026-5090","details":"Template::Plugin::HTML versions before 3.103 for Perl allows HTML and JavaScript to be injected.  The html_filter function did not escape single quotes. HTML attributes inside of single quotes could be have code injected.  For example, the variable \"var\" in      \u003ca id='ref' title='[% var | html %]'\u003e  would not be properly escaped. An attacker could insert some limited HTML and JavaScript, for example,      var = \" ' onclick='while (true) { alert(1) }'\"  Note that arbitrary HTML and JavaScript would be difficult to inject, because angle brackets, ampersands and double-quotes would still be escaped.","modified":"2026-09-20T08:47:29.911921326Z","published":"2026-05-19T22:16:39.003Z","upstream":["CVE-2026-5090"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-5090"}],"affected":[{"package":{"name":"libtemplate-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libtemplate-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.27-1","3.102-1","3.102-2","3.102-3","3.106-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-5090.json"}},{"package":{"name":"libtemplate-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libtemplate-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.27-1","3.102-1","3.102-2","3.102-3","3.106-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-5090.json"}},{"package":{"name":"libtemplate-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libtemplate-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.102-3"}]}],"versions":["2.27-1","3.102-1","3.102-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-5090.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
