An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-50171 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @angular/common (npm): affected all versions up to 18.2.14; no fix listed\n- @angular/common (npm): affected all versions up to 18.2.14; no fix listed\n- @angular/common (npm): affected from 19.0.0-next.0; fixed in 19.2.23\n- @angular/common (npm): affected from 19.0.0-next.0; fixed in 19.2.23\n- @angular/common (npm): affected from 20.0.0-next.0; fixed in 20.3.22\n- @angular/common (npm): affected from 20.0.0-next.0; fixed in 20.3.22\n- @angular/common (npm): affected from 21.0.0-next.0; fixed in 21.2.15\n- @angular/common (npm): affected from 21.0.0-next.0; fixed in 21.2.15\n- @angular/common (npm): affected from 22.0.0-next.0; fixed in 22.0.0-rc.2\n- @angular/common (npm): affected from 22.0.0-next.0; fixed in 22.0.0-rc.2\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-2026-50171/ (Markdown: https://insights.sbomify.com/CVE-2026-50171/index.md)","id":"CVE-2026-50171","markdown":"https://insights.sbomify.com/CVE-2026-50171/index.md","name":"CVE-2026-50171","record":{"aliases":["DEBIAN-CVE-2026-50171","GHSA-p3vc-36g9-x9gr","UBUNTU-CVE-2026-50171"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Angular web framework","requires_auth":"none","summary":"Attackers can cause a Denial of Service via Out-of-Memory errors in Angular's number formatting functions by providing maliciously crafted digit information parameters.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"angular","vendor":"angular"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-834","name":"Excessive Iteration"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23, a Denial of Service (DoS) vulnerability exists in the @angular/common package of Angular. The formatNumber function, which is also utilized by DecimalPipe, PercentPipe, and CurrencyPipe, does not properly validate the upper bounds of the digitsInfo parameter. Specifically, the minimum and maximum fraction digits parsed from the digitsInfo string (e.g., 1.2-4) are converted to integers and used without limits. When parsing a maliciously crafted digitsInfo string with excessively large fraction digit values (e.g., 1.200000000-200000000), the internal roundNumber function attempts to pad the digits array to match the requested fraction size. This results in an unbounded loop that repeatedly pushes elements into an array.  This vulnerability is fixed in 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23.","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: Denial of Service (DoS) via OOM in Number Formatting (digitsInfo)","id":"CVE-2026-50171","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":10,"n_references":1,"next":{"headline":"Flow-Like: Azure invoke presign grants app content write SAS to ExecuteEvents-only users","id":"CVE-2026-50173"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["18.2.14"],"package":"@angular/common","purl":null,"source":"GHSA-p3vc-36g9-x9gr"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["18.2.14"],"package":"@angular/common","purl":"pkg:npm/%40angular/common","source":"GHSA-p3vc-36g9-x9gr"},{"ecosystem":"npm","fixed":["19.2.23"],"introduced":["19.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":null,"source":"GHSA-p3vc-36g9-x9gr"},{"ecosystem":"npm","fixed":["19.2.23"],"introduced":["19.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":"pkg:npm/%40angular/common","source":"GHSA-p3vc-36g9-x9gr"},{"ecosystem":"npm","fixed":["20.3.22"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":null,"source":"GHSA-p3vc-36g9-x9gr"},{"ecosystem":"npm","fixed":["20.3.22"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":"pkg:npm/%40angular/common","source":"GHSA-p3vc-36g9-x9gr"},{"ecosystem":"npm","fixed":["21.2.15"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":null,"source":"GHSA-p3vc-36g9-x9gr"},{"ecosystem":"npm","fixed":["21.2.15"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":"pkg:npm/%40angular/common","source":"GHSA-p3vc-36g9-x9gr"},{"ecosystem":"npm","fixed":["22.0.0-rc.2"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":null,"source":"GHSA-p3vc-36g9-x9gr"},{"ecosystem":"npm","fixed":["22.0.0-rc.2"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":"pkg:npm/%40angular/common","source":"GHSA-p3vc-36g9-x9gr"}],"prev":{"headline":"Angular: Information Leak via Default Caching of Credentialed Requests in HttpTransferCache","id":"CVE-2026-50170"},"products":["angular"],"published":"2026-06-22","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-23","vendors":["angular"]},"summary":"Attackers can cause a Denial of Service via Out-of-Memory errors in Angular's number formatting functions by providing maliciously crafted digit information parameters.","url":"https://insights.sbomify.com/CVE-2026-50171/"}
