{"apiVersion":"1.0","identifier":"CVE-2026-81101","description":"The configure command accepted any endpoint URL and stored it beside the user-s access token. ConfigureCommand.execute in src/cli.ts persisted the value given to its endpoint option into the user profile without passing it through createSafeUrl in src/config.ts, the helper that already restricted the environment-variable form of the same setting to the vendor-s own hosts over HTTPS. Because the connect path in src/mcp.ts attaches the stored token as a bearer credential on every request to the configured endpoint, a user who was persuaded to run configure with an endpoint of the attacker-s choosing sent their personal access token to that destination on each subsequent invocation. Version 0.2.5 applies the same helper to the option.","publishedAt":"2026-08-27T17:20:52","lastModifiedAt":"2026-08-27T20:18:49","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81101","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","epssProbability":0.00322,"riskScore":0.67,"affectedProduct":"tiger-gh-mcp-server","affectedVersions":"<0.2.5","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81101","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81101","en":"https://www.redsauce.net/en/cves/CVE-2026-81101","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81101","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81101","de":"https://www.redsauce.net/de/cves/CVE-2026-81101","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81101","el":"https://www.redsauce.net/el/cves/CVE-2026-81101"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81101"}}
