There is a prototype pollution vulnerability in aurelia-path before version 1.1.7. The vulnerability exposes Aurelia application that uses `aurelia-path` package to parse a string. The majority of this will be Aurelia applications that employ the `aurelia-router` package. An example is this could allow an attacker to change the prototype of base object class `Object` by tricking an application to parse the following URL: `https://aurelia.io/blog/?__proto__[asdf]=asdf`. The problem is patched in version `1.1.7`.","published_at":"2021-09-27T17:40:12Z","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":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-1321"],"nvd_references":["https://github.com/aurelia/path/security/advisories/GHSA-3c9c-2p65-qvwv","https://github.com/aurelia/path/issues/44","https://github.com/aurelia/path/commit/7c4e235433a4a2df9acc313fbe891758084fdec1","https://github.com/aurelia/path/releases/tag/1.1.7","https://www.npmjs.com/package/aurelia-path"],"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":"2026-06-28T23:16:12.047589Z"},"effective_severity":"CRITICAL","badges":["poc"],"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":"aurelia","vendor_name":"aurelia","product_slug":"path","product_name":"path","version_start":"< 1.1.7","version_start_inclusive":true,"version_end":"< 1.1.7","version_end_inclusive":true,"cpe23_uri":"cve5:aurelia:path:< 1.1.7:< 1.1.7"}],"exploit_refs":[{"source":"nuclei","kind":"nuclei","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2021/CVE-2021-41097.yaml","title":"Aurelia-Path < 1.1.7 - Prototype Pollution","author":"0x_Akoko","disclosed_at":null}],"news":[],"references":[{"url":"https://github.com/aurelia/path/security/advisories/GHSA-3c9c-2p65-qvwv","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/aurelia/path/issues/44","source_type":"MISC","tags":[]},{"url":"https://github.com/aurelia/path/commit/7c4e235433a4a2df9acc313fbe891758084fdec1","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/aurelia/path/releases/tag/1.1.7","source_type":"PATCH","tags":["patch"]},{"url":"https://www.npmjs.com/package/aurelia-path","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2021-09-27T17:40:12Z","label":"CVE published","source":null},{"type":"poc_available","at":"2026-06-24T00:29:48.638073Z","label":"Public PoC available","source":"nuclei"},{"type":"cvss_changed","at":"2026-06-28T17:19:30.643420Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:19:30.643420Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:19:30.643420Z","label":"CVSS score revised","source":"cvelistv5"}]}
