{“lastseen”:””,”description”:”samlify is a Node.js library for SAML single sign-on. Prior to version 2.13.0, samlify\u2019s template substitution only escapes attribute contexts. Values inserted into element text (e.g., \\u003csaml:AttributeValue\\u003e) are not escaped. A normal user can inject XML markup into an attribute value (e.g., email, name) and add new \\u003csaml:Attribute\\u003e elements inside the signed assertion. The IdP then signs the tampered assertion and the SP accepts the injected attributes as trusted. This allows privilege escalation when attributes are used for authorization (roles\/groups). This issue has been patched in version 2.13.0.”,”published”:”2026-06-08T18:41:40.145Z”,”modified”:”2026-06-08T18:41:40.145Z”,”type”:”cve”,”title”:”samlify: XML Injection in AttributeValue Allows Privilege Escalation in Signed SAML Assertions”,”source”:”GitHub_M”,”references”:”https:\/\/github.com\/tngan\/samlify\/security\/advisories\/GHSA-34r5-q4jw-r36m”,”id”:”CVE-2026-46490″,”bulletinFamily”:””,”cwe”:[“CWE-91″],”cvelist”:null,”sourceData”:”tngan samlify \\u003c 2.13.0″,”sourceHref”:””,”cvss”:{“score”:8.7,”severity”:”HIGH”,”vector”:”CVSS:4.0\/AV:N\/AC:L\/AT:N\/PR:N\/UI:N\/VC:N\/VI:H\/VA:N\/SC:N\/SI:N\/SA:N”,”version”:”4.0″},”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”:””,”category_name”:”CVE”,”post_link”:””,”product”:”samlify”,”version”:”\\u003c 2.13.0″,”vendor”:”tngan”,”ai_description”:”XML Injection vulnerability in samlify allows privilege escalation in signed SAML assertions”,”ai_severity”:”High”,”ai_vendor”:”tngan”,”ai_product”:”samlify”,”ai_version”:”\\u003c 2.13.0″,”ai_score”:8.7}<\/p>\n","protected":false},"excerpt":{"rendered":"
