Prior to version 4.2.0, crypto-js PBKDF2 is 1,000 times weaker than originally specified in 1993, and at least 1,300,000 times weaker than current industry standard. This is because it both defaults to SHA1, a cryptographic hash algorithm considered insecure since at least 2005, and defaults to one single iteration, a 'strength' or 'difficulty' value specified at 1,000 when specified in 1993. PBKDF2 relies on iteration count as a countermeasure to preimage and collision attacks. If used to protect passwords, the impact is high. If used to generate signatures, the impact is high. Version 4.2.0 contains a patch for this issue. As a workaround, configure crypto-js to use SHA256 with at least 250,000 iterations.","published_at":"2023-10-25T20:49:31.582000Z","last_modified_at":null,"cvss_v3_score":9.1,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":true,"ssvc_technical_impact":"total","cwes":["CWE-328","CWE-916"],"nvd_references":["https://github.com/brix/crypto-js/security/advisories/GHSA-xwcq-pm8m-c4vf","https://github.com/brix/crypto-js/commit/421dd538b2d34e7c24a5b72cc64dc2b9167db40a","https://lists.debian.org/debian-lts-announce/2023/11/msg00025.html"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:39:28.500535Z"},"effective_severity":"CRITICAL","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"brix","vendor_name":"brix","product_slug":"crypto-js","product_name":"crypto-js","version_start":"< 4.2.0","version_start_inclusive":true,"version_end":"< 4.2.0","version_end_inclusive":true,"cpe23_uri":"cve5:brix:crypto-js:< 4.2.0:< 4.2.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/brix/crypto-js/security/advisories/GHSA-xwcq-pm8m-c4vf","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/brix/crypto-js/commit/421dd538b2d34e7c24a5b72cc64dc2b9167db40a","source_type":"PATCH","tags":["patch"]},{"url":"https://lists.debian.org/debian-lts-announce/2023/11/msg00025.html","source_type":"MAILING_LIST","tags":["mailing-list"]}],"timeline":[{"type":"published","at":"2023-10-25T20:49:31.582000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:30:22.759310Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:30:22.759310Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:30:22.759310Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:39:28.500535Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:39:28.500535Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:39:28.500535Z","label":"SSVC decision revised","source":"vulnrichment"}]}
