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-2026-88056 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-2026-88056/ (Markdown: https://insights.sbomify.com/CVE-2026-88056/index.md)","id":"CVE-2026-88056","markdown":"https://insights.sbomify.com/CVE-2026-88056/index.md","name":"CVE-2026-88056","record":{"aliases":["DEBIAN-CVE-2026-88056","GHSA-f6mr-pjwc-34m4","UBUNTU-CVE-2026-88056"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Angular SSR library","requires_auth":"none","summary":"Attackers can exploit URL parsing discrepancies in Angular SSR to trigger SSRF and disclose sensitive server-side credentials.","user_interaction":"required","vuln_class":"ssrf"},"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-918","name":"Server-Side Request Forgery"}],"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 in @angular/platform-server processes user-controlled resource or request URLs through HttpClient after application code validates them with WHATWG URL parsing. The resolveUrl and parseUrl utilities called String.prototype.trim(), which removed leading Unicode whitespace such as U+00A0 or U+FEFF after the input passed a same-origin check, converting a relative path into a protocol-relative attacker-controlled URL. In affected applications that attach sensitive server-side credentials such as Authorization headers to approved requests, relativeUrlsTransformerInterceptorFn then dispatched the request to the attacker-controlled origin, causing SSRF and credential disclosure.
