An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-88057 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @angular/compiler (npm): affected all versions up to 19.2.25; no fix listed\n- @angular/compiler (npm): affected all versions up to 19.2.25; no fix listed\n- @angular/compiler (npm): affected from 20.0.0; fixed in 20.3.28\n- @angular/compiler (npm): affected from 20.0.0; fixed in 20.3.28\n- @angular/compiler (npm): affected from 21.0.0; fixed in 21.2.20\n- @angular/compiler (npm): affected from 21.0.0; fixed in 21.2.20\n- @angular/compiler (npm): affected from 22.0.0; fixed in 22.1.0\n- @angular/compiler (npm): affected from 22.0.0; fixed in 22.1.0\n- @angular/core (npm): affected all versions up to 19.2.25; no fix listed\n- @angular/core (npm): affected all versions up to 19.2.25; no fix listed\n- @angular/core (npm): affected from 20.0.0; fixed in 20.3.28\n- @angular/core (npm): affected from 20.0.0; fixed in 20.3.28\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-2026-88057/ (Markdown: https://insights.sbomify.com/CVE-2026-88057/index.md)","id":"CVE-2026-88057","markdown":"https://insights.sbomify.com/CVE-2026-88057/index.md","name":"CVE-2026-88057","record":{"aliases":["CLSA-2026-1790416421","CLSA-2026-1790431292","CLSA-2026-1790444995","CLSA-2026-1790468982","CLSA-2026-1790479328","CLSA-2026-1792161348","CLSA-2026-1792163742","CLSA-2026-1792208276","CLSA-2026-1792250344","CLSA-2026-1792281394","CLSA-2026-1792325613","CLSA-2026-1792345414","CLSA-2026-1792357501","CLSA-2026-1792366720","CLSA-2026-1792371788","CLSA-2026-1792375868","CLSA-2026-1792380177","CLSA-2026-1792382747","CLSA-2026-1792386236","DEBIAN-CVE-2026-88057","GHSA-hh8m-fm6v-7cvg","UBUNTU-CVE-2026-88057"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Angular framework","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in user browsers by bypassing Angular's sanitization on specific host bindings, affecting all Angular applications.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"angular","vendor":"angular"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.28, 21.2.20, and 22.1.0, Angular's compiler and runtime in @angular/core and @angular/compiler could omit or select an incorrect sanitizer for security-sensitive directive host bindings because SecurityContext was derived from the declaring directive or component selector rather than the concrete host element. The mismatch is reachable through hostDirectives composition, inherited HostBinding declarations, createComponent with a custom hostElement or dynamic directives, SVG/MathML namespace elements, and tag-neutral selectors such as :not(...). Attacker-controlled href, src, action, xlink:href, or data values can therefore reach DOM attributes without Angular's built-in sanitizer and execute arbitrary JavaScript in the user's browser context. Applications unable to upgrade can use DomSanitizer.sanitize with SecurityContext.URL before assignment or restrict inputs to validated HTTP and HTTPS URL schemes. This issue is fixed in versions 20.3.28, 21.2.20, and 22.1.0.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Angular:
