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-2026-54268 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @angular/common (npm): affected all versions up to 19.2.25; no fix listed\n- @angular/common (npm): affected all versions up to 19.2.25; no fix listed\n- @angular/common (npm): affected from 20.0.0-next.0; fixed in 20.3.25\n- @angular/common (npm): affected from 20.0.0-next.0; fixed in 20.3.25\n- @angular/common (npm): affected from 21.0.0-next.0; fixed in 21.2.17\n- @angular/common (npm): affected from 21.0.0-next.0; fixed in 21.2.17\n- @angular/common (npm): affected from 22.0.0-next.0; fixed in 22.0.1\n- @angular/common (npm): affected from 22.0.0-next.0; fixed in 22.0.1\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-2026-54268/ (Markdown: https://insights.sbomify.com/CVE-2026-54268/index.md)","id":"CVE-2026-54268","markdown":"https://insights.sbomify.com/CVE-2026-54268/index.md","name":"CVE-2026-54268","record":{"aliases":["DEBIAN-CVE-2026-54268","GHSA-48r7-hpm6-gfxm","UBUNTU-CVE-2026-54268"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Angular framework","requires_auth":"none","summary":"Attackers can cause denial of service in Angular applications by supplying excessively long date format strings to the formatDate function, leading to resource exhaustion.","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-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.1, 21.2.17, and 20.3.25, a Denial of Service (DoS) vulnerability exists in the @angular/common package of the Angular framework. The formatDate function, which is also utilized by the standard Angular DatePipe, does not properly limit or validate the length of the format parameter. When parsing a maliciously crafted, excessively long date format string (e.g., a repeating pattern or very large string), the internal parser splits the string iteratively using a regular expression loop. This results in uncontrolled resource consumption (high CPU utilization and excessive memory allocations), leading to a Denial of Service (DoS). This vulnerability is fixed in 22.0.1, 21.2.17, and 20.3.25.","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 Date Formatting (formatDate)","id":"CVE-2026-54268","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":8,"n_references":3,"next":{"headline":"protobufjs: Schema-derived names can shadow runtime-significant properties","id":"CVE-2026-54269"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["19.2.25"],"package":"@angular/common","purl":null,"source":"GHSA-48r7-hpm6-gfxm"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["19.2.25"],"package":"@angular/common","purl":"pkg:npm/%40angular/common","source":"GHSA-48r7-hpm6-gfxm"},{"ecosystem":"npm","fixed":["20.3.25"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":null,"source":"GHSA-48r7-hpm6-gfxm"},{"ecosystem":"npm","fixed":["20.3.25"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":"pkg:npm/%40angular/common","source":"GHSA-48r7-hpm6-gfxm"},{"ecosystem":"npm","fixed":["21.2.17"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":null,"source":"GHSA-48r7-hpm6-gfxm"},{"ecosystem":"npm","fixed":["21.2.17"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":"pkg:npm/%40angular/common","source":"GHSA-48r7-hpm6-gfxm"},{"ecosystem":"npm","fixed":["22.0.1"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":null,"source":"GHSA-48r7-hpm6-gfxm"},{"ecosystem":"npm","fixed":["22.0.1"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/common","purl":"pkg:npm/%40angular/common","source":"GHSA-48r7-hpm6-gfxm"}],"prev":{"headline":"Angular Client Hydration DOM Clobbering \u0026 Response-Cache Poisoning","id":"CVE-2026-54267"},"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 denial of service in Angular applications by supplying excessively long date format strings to the formatDate function, leading to resource exhaustion.","url":"https://insights.sbomify.com/CVE-2026-54268/"}
