In versions 0.1.0 through 2.3.1, when using OpenBao's userpass auth method, user enumeration was possible due to timing difference between non-existent users and users with stored credentials. This is independent of whether the supplied credentials were valid for the given user. This issue was fixed in version 2.3.2. To work around this issue, users may use another auth method or apply rate limiting quotas to limit the number of requests in a period of time: https://openbao.org/api-docs/system/rate-limit-quotas/.","status":"published","published":"2026-07-27T05:48:54.126Z","modified":"2026-09-08T08:48:16.727634155Z","updated_at":"2026-11-02T15:28:34.343258Z"},{"id":"GO-2025-3854","title":"OpenBao has a Timing Side-Channel in the Userpass Auth Method in github.com/openbao/openbao","description":"OpenBao has a Timing Side-Channel in the Userpass Auth Method in github.com/openbao/openbao.\n\nNOTE: The source advisory for this report contains additional versions that could not be automatically mapped to standard Go module versions.\n\n(If this is causing false-positive reports from vulnerability scanners, please suggest an edit to the report.)\n\nThe additional affected modules and versions are: github.com/openbao/openbao before v2.3.2.","status":"published","published":"2025-08-11T17:59:12Z","modified":"2026-07-27T09:11:30.793253592Z","updated_at":"2026-11-02T15:47:01.728182Z"},{"id":"openSUSE-SU-2025:15434-1","title":"govulncheck-vulndb-0.0.20250811T192933-1.1 on GA media","description":"These are all security issues fixed in the govulncheck-vulndb-0.0.20250811T192933-1.1 package on the GA media of openSUSE Tumbleweed.","status":"published","published":"2025-08-12T00:00:00Z","modified":"2026-03-23T04:53:46.634804Z","updated_at":"2026-11-02T16:58:37.810934Z"},{"id":"SUSE-SU-2025:02912-1","title":"Security update for govulncheck-vulndb","description":"This update for govulncheck-vulndb fixes the following issues:\n\n- Update to version 0.0.20250814T182633 2025-08-14T18:26:33Z (jsc#PED-11136)\n\n  Go CVE Numbering Authority IDs added or updated with aliases:\n  * GO-2025-3765 CVE-2024-44906 GHSA-h4h6-vccr-44h2\n  * GO-2025-3829 CVE-2025-54410 GHSA-4vq8-7jfc-9cvp\n\n- Update to version 0.0.20250811T192933 2025-08-11T19:29:33Z (jsc#PED-11136)\n  \n  Go CVE Numbering Authority IDs added or updated with aliases:\n  * GO-2025-3822 CVE-2025-53942 GHSA-9g4j-v8w5-7x42\n  * GO-2025-3829 CVE-2025-54410 GHSA-4vq8-7jfc-9cvp\n  * GO-2025-3830 CVE-2025-54388 GHSA-x4rx-4gw3-53p4\n  * GO-2025-3831 CVE-2025-50738 GHSA-hfcf-79gh-f3jc\n  * GO-2025-3832 CVE-2021-21411 GHSA-652x-m2gr-hppm\n  * GO-2025-3833 CVE-2025-54576 GHSA-7rh7-c77v-6434\n  * GO-2025-3834 CVE-2025-54424 GHSA-8j63-96wh-wh3j\n  * GO-2025-3835 CVE-2025-54386 GHSA-q6gg-9f92-r9wg\n  * GO-2025-3836 CVE-2025-6037 GHSA-6c5r-4wfc-3mcx\n  * GO-2025-3837 CVE-2025-5999 GHSA-6h4p-m86h-hhgh\n  * GO-2025-3838 CVE-2025-6000 GHSA-mr4h-qf9j-f665\n  * GO-2025-3839 CVE-2025-6011 GHSA-mwgr-84fv-3jh9\n  * GO-2025-3840 CVE-2025-6004 GHSA-qgj7-fmq2-6cc4\n  * GO-2025-3841 CVE-2025-6014 GHSA-qv3p-fmv3-9hww\n  * GO-2025-3842 CVE-2025-6015 GHSA-v6r4-35f9-9rpw\n  * GO-2025-3843 CVE-2025-8341 GHSA-3c93-92r7-j934\n  * GO-2025-3844 CVE-2025-53534 GHSA-fm3m-jrgm-5ppg\n  * GO-2025-3845 CVE-2025-54801 GHSA-qx2q-88mx-vhg7\n  * GO-2025-3847 CVE-2025-54799 GHSA-q82r-2j7m-9rv4\n  * GO-2025-3848 CVE-2025-6013 GHSA-7rx2-769v-hrwf\n  * GO-2025-3851 CVE-2025-44779 GHSA-93jv-pvg8-hf3v\n  * GO-2025-3852 CVE-2025-7195 GHSA-856v-8qm2-9wjv\n  * GO-2025-3853 CVE-2025-55000 GHSA-f7c3-mhj2-9pvg\n  * GO-2025-3854 CVE-2025-54999 GHSA-hh28-h22f-8357\n  * GO-2025-3855 CVE-2025-54998 GHSA-j3xv-7fxp-gfhx\n  * GO-2025-3856 CVE-2025-55003 GHSA-rxp7-9q75-vj3p\n  * GO-2025-3857 CVE-2025-54996 GHSA-vf84-mxrq-crqc\n  * GO-2025-3858 CVE-2025-54997 GHSA-xp75-r577-cvhp\n  * GO-2025-3859 CVE-2025-55001 GHSA-2q8q-8fgw-9p6p\n\n- Update to version 0.0.20250807T150727 2025-08-07T15:07:27Z (jsc#PED-11136)\n\n  Go CVE Numbering Authority IDs added or updated with aliases:\n  * GO-2025-3849 CVE-2025-47907\n","status":"published","published":"2025-08-19T12:52:27Z","modified":"2026-03-23T04:49:48.54789Z","updated_at":"2026-11-02T15:53:57.111474Z"}]}}
