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-2022-25758 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- scss-tokenizer (npm): affected all versions; fixed in 0.4.3\n- scss-tokenizer (npm): affected all versions; fixed in 0.4.3\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-2022-25758/ (Markdown: https://insights.sbomify.com/CVE-2022-25758/index.md)","id":"CVE-2022-25758","markdown":"https://insights.sbomify.com/CVE-2022-25758/index.md","name":"CVE-2022-25758","record":{"aliases":["CLSA-2026-1776991068","CLSA-2026-1788167387","GHSA-7mwh-4pqv-wmr8","UBUNTU-CVE-2022-25758"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"npm scss tokenizer","requires_auth":"none","summary":"Attackers can cause denial of service in applications using scss-tokenizer by exploiting insecure regular expressions in the loadAnnotation function.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"scss-tokenizer","vendor":"scss-tokenizer_project"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"All versions of package scss-tokenizer are vulnerable to Regular Expression Denial of Service (ReDoS) via the loadAnnotation() function, due to the usage of insecure regex.","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":"Regular Expression Denial of Service (ReDoS)","id":"CVE-2022-25758","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":2,"n_references":3,"next":{"headline":"Remote Code Injection","id":"CVE-2022-25759"},"packages":[{"ecosystem":"npm","fixed":["0.4.3"],"introduced":["0"],"last_affected":[],"package":"scss-tokenizer","purl":null,"source":"GHSA-7mwh-4pqv-wmr8"},{"ecosystem":"npm","fixed":["0.4.3"],"introduced":["0"],"last_affected":[],"package":"scss-tokenizer","purl":"pkg:npm/scss-tokenizer","source":"GHSA-7mwh-4pqv-wmr8"}],"prev":{"headline":"Apache APISIX: the body_schema check in request-validation plugin can be bypassed","id":"CVE-2022-25757"},"products":["scss-tokenizer"],"published":"2022-07-01","related":[],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["n/a"]},"summary":"Attackers can cause denial of service in applications using scss-tokenizer by exploiting insecure regular expressions in the loadAnnotation function.","url":"https://insights.sbomify.com/CVE-2022-25758/"}
