{"id":"CVE-2022-43756","aliases":["GHSA-8fcj-gf77-47mg","GO-2023-1515"],"url":"https://o3.security/vulnerability/CVE-2022-43756","summary":"Rancher/Wrangler: Denial of service when processing Git credentials","details":"### Impact\n\nA denial of services (DoS) vulnerability was discovered in Wrangler Git package affecting versions up to and including `v1.0.0`.\n\nSpecially crafted Git credentials can result in a denial of service (DoS) attack on an application that uses Wrangler due to the exhaustion of the available memory and CPU resources. This is caused by a lack of input validation of Git credentials before they are used, which may lead to a denial of service in some cases. This issue can be triggered when accessing both private and public Git repositories. \n\n### Workarounds\n\nA workaround is to sanitize input passed to the Git package to remove potential unsafe and ambiguous characters. Otherwise, the best course of action is to update to a patched Wrangler version.\n\n### Patches\n\nPatched versions include `v1.0.1` and later and the backported tags - `v0.7.4-security1`, `v0.8.5-security1` and `v0.8.11`.\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Reach out to [SUSE Rancher Security team](https://github.com/rancher/rancher/security/policy) for security related inquiries.\n* Open an issue in [Rancher](https://github.com/rancher/rancher/issues/new/choose) or [Wrangler](https://github.com/rancher/wrangler/issues/new) repository.\n* Verify our [support matrix](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/) and [product support lifecycle](https://www.suse.com/lifecycle/).","published":"2023-02-07T00:00:00Z","modified":"2026-08-12T03:51:30.066709913Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:H"},"epss":{"score":0.00684,"percentile":0.50961,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/rancher/wrangler","fixedVersion":"0.7.4-security1"},{"ecosystem":"Go","name":"github.com/rancher/wrangler","fixedVersion":"0.8.5-security1"},{"ecosystem":"Go","name":"github.com/rancher/wrangler","fixedVersion":"1.0.1"},{"ecosystem":"Go","name":"github.com/rancher/wrangler","fixedVersion":"0.8.11"}],"fix":{"url":"https://github.com/rancher/wrangler/commit/341018c8fef3e12867c7cb2649bd2cecac75f287","label":"rancher/wrangler@341018c"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/43xxx/CVE-2022-43756.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-43756"},{"type":"REPORT","url":"https://bugzilla.suse.com/show_bug.cgi?id=1205296"},{"type":"WEB","url":"https://github.com/rancher/wrangler/security/advisories/GHSA-8fcj-gf77-47mg"},{"type":"WEB","url":"https://github.com/rancher/wrangler/commit/341018c8fef3e12867c7cb2649bd2cecac75f287"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-8fcj-gf77-47mg"},{"type":"WEB","url":"https://github.com/rancher/rancher/security/policy"},{"type":"PACKAGE","url":"https://github.com/rancher/wrangler"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2023-1515"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:30.066709913Z"}}
