Prior to 2.5.2, Apollo ConfigService may allow unauthorized access to configuration data when AccessKey or management key authentication is enabled because ConfigService can accept a non-canonical appId variant during authentication while downstream request handling resolves it to the protected app, including accent variants under accent-insensitive collations or trailing-space variants under PAD SPACE collations on /configs and /configfiles endpoints. This issue is fixed in version 2.5.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-20","CWE-287"],"references":["https://github.com/apolloconfig/apollo/commit/310809d557e01c6803051736cd525e333ffe00ec","https://github.com/apolloconfig/apollo/releases/tag/v2.5.2","https://github.com/apolloconfig/apollo/security/advisories/GHSA-4w3q-qpfq-v992"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-59954","score":0.00574,"percentile":0.47106,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4w3q-qpfq-v992","url":"https://osv.dev/vulnerability/GHSA-4w3q-qpfq-v992","summary":"Apollo ConfigService access key authentication bypass via appId parsing and non-canonical matching","modified":"2026-07-20T19:30:24.097447054Z","packages":[{"ecosystem":"Maven","name":"com.ctrip.framework.apollo:apollo","purl":"pkg:maven/com.ctrip.framework.apollo/apollo","ranges":["<=2.0.1"],"fixed":[]}]}],"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).
