An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-88060 exists.\n\nAffected packages and fixed versions:\n- @angular/platform-server (npm): affected all versions up to 19.2.25; no fix listed\n- @angular/platform-server (npm): affected all versions up to 19.2.25; no fix listed\n- @angular/platform-server (npm): affected from 20.0.0; fixed in 20.3.30\n- @angular/platform-server (npm): affected from 20.0.0; fixed in 20.3.30\n- @angular/platform-server (npm): affected from 21.0.0; fixed in 21.2.22\n- @angular/platform-server (npm): affected from 21.0.0; fixed in 21.2.22\n- @angular/platform-server (npm): affected from 22.0.0; fixed in 22.1.4\n- @angular/platform-server (npm): affected from 22.0.0; fixed in 22.1.4\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-88060/ (Markdown: https://insights.sbomify.com/CVE-2026-88060/index.md)","id":"CVE-2026-88060","markdown":"https://insights.sbomify.com/CVE-2026-88060/index.md","name":"CVE-2026-88060","record":{"aliases":["DEBIAN-CVE-2026-88060","GHSA-v3p8-whq6-r5jg","UBUNTU-CVE-2026-88060"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Angular SSR library","requires_auth":"none","summary":"Angular SSR fails to escape template content in fallback raw-content elements, allowing attackers to inject arbitrary JavaScript via unescaped closing tags.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"angular","vendor":"angular"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.30, 21.2.22, and 22.1.4, Angular server-side rendering (SSR) in @angular/platform-server serializes untrusted input inside template content nested in fallback raw-content elements such as noscript, iframe, noembed, and noframes. The Domino serializer's fallbackRawContentTags traversal stopped at the DocumentFragment used by template.content, so matching closing tags in xmp, style, script, comments, or text nodes were not escaped. Standard interpolation with comments or text nodes is reachable without relaxed schemas; literal xmp or style requires CUSTOM_ELEMENTS_SCHEMA or NO_ERRORS_SCHEMA, while Renderer2 imperative DOM construction is unconditionally affected. When HTML5 RAWTEXT browser parsing encounters the unescaped closing tag, it exits the fallback container and interprets trailing markup as active DOM elements, enabling arbitrary JavaScript execution. This issue is fixed in versions 20.3.30, 21.2.22, and 22.1.4.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Angular: SSR XSS via Unescaped \u003ctemplate\u003e Content Across DocumentFragment Boundaries in Fallback Raw-Content Elements","id":"CVE-2026-88060","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":8,"n_references":8,"next":{"headline":"Cross-site request forgery in career-ops","id":"CVE-2026-88061"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["19.2.25"],"package":"@angular/platform-server","purl":null,"source":"GHSA-v3p8-whq6-r5jg"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["19.2.25"],"package":"@angular/platform-server","purl":"pkg:npm/%40angular/platform-server","source":"GHSA-v3p8-whq6-r5jg"},{"ecosystem":"npm","fixed":["20.3.30"],"introduced":["20.0.0"],"last_affected":[],"package":"@angular/platform-server","purl":null,"source":"GHSA-v3p8-whq6-r5jg"},{"ecosystem":"npm","fixed":["20.3.30"],"introduced":["20.0.0"],"last_affected":[],"package":"@angular/platform-server","purl":"pkg:npm/%40angular/platform-server","source":"GHSA-v3p8-whq6-r5jg"},{"ecosystem":"npm","fixed":["21.2.22"],"introduced":["21.0.0"],"last_affected":[],"package":"@angular/platform-server","purl":null,"source":"GHSA-v3p8-whq6-r5jg"},{"ecosystem":"npm","fixed":["21.2.22"],"introduced":["21.0.0"],"last_affected":[],"package":"@angular/platform-server","purl":"pkg:npm/%40angular/platform-server","source":"GHSA-v3p8-whq6-r5jg"},{"ecosystem":"npm","fixed":["22.1.4"],"introduced":["22.0.0"],"last_affected":[],"package":"@angular/platform-server","purl":null,"source":"GHSA-v3p8-whq6-r5jg"},{"ecosystem":"npm","fixed":["22.1.4"],"introduced":["22.0.0"],"last_affected":[],"package":"@angular/platform-server","purl":"pkg:npm/%40angular/platform-server","source":"GHSA-v3p8-whq6-r5jg"}],"prev":{"headline":"Angular: Information Leak via `HttpTransferCache` Bypass When Using `withRequestsMadeViaParent`","id":"CVE-2026-88059"},"products":["angular"],"published":"2026-09-10","related":[{"cvss_score":8.8,"headline":"Angular: Cache-Key Ambiguity in HttpTransferCache Leading to Cross-Request Response Reuse and State Poisoning","id":"CVE-2026-68945","kev_date_added":null,"published":"2026-08-03"},{"cvss_score":8.8,"headline":"Angular: SSRF via Hostname Hijacking in @angular/platform-server","id":"CVE-2026-46417","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":8.8,"headline":"Angular: URL Parser Differential in @angular/platform-server leading to SSRF Allowlist Bypass","id":"CVE-2026-50168","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":8.8,"headline":"Angular: Weak 32-Bit Cache Key Hashing in `HttpTransferCache` Leading to Cross-Request Data Leakage and State Poisoning","id":"CVE-2026-54266","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":8.7,"headline":"Angular: SSRF via protocol-relative and backslash URLs in Angular Platform-Server","id":"CVE-2026-41423","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":8.6,"headline":"Angular: SSRF and Cross-Origin Credential Disclosure via URL Resolution Discrepancy in SSR","id":"CVE-2026-88056","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Angular: SSR XSS via Unescaped Processing Instruction (\u003c?...?\u003e) Nodes in Fallback Raw-Content Elements","id":"CVE-2026-88058","kev_date_added":null,"published":"2026-09-10"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-10","vendors":["angular"]},"summary":"Angular SSR fails to escape template content in fallback raw-content elements, allowing attackers to inject arbitrary JavaScript via unescaped closing tags.","url":"https://insights.sbomify.com/CVE-2026-88060/"}
