If the client checks the cache when attempting to perform the next update, the update timestamp validation will fail, preventing the next update until the cache is cleared. Users should upgrade to tough version 0.20.0 or later and ensure any forked or derivative code is patched to incorporate the new fixes.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:P/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":5.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:N","score":4.5},"cwes":["CWE-1025"],"references":["https://aws.amazon.com/security/security-bulletins/AWS-2025-007/","https://github.com/awslabs/tough/releases/tag/tough-v0.20.0","https://github.com/awslabs/tough/security/advisories/GHSA-76g3-38jv-wxh4"],"products":["amazon:tough"],"source":"nvd","synced_at":"2026-10-19T22:00:28.034033815+00:00"},"epss":{"cve":"CVE-2025-2888","score":0.00332,"percentile":0.26491,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-76g3-38jv-wxh4","url":"https://osv.dev/vulnerability/GHSA-76g3-38jv-wxh4","summary":"tough timestamp metadata is cached when it fails snapshot rollback check","modified":"2025-10-14T21:59:01Z","packages":[{"ecosystem":"crates.io","name":"tough","purl":"pkg:cargo/tough","ranges":["<0.20.0"],"fixed":["0.20.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
