{"apiVersion":"1.0","identifier":"CVE-2026-48105","description":"Arc is an open, SQL-native time-series database for telemetry. Prior to version 26.06.1, Arc Enterprise-s Raft FSM (`internal/cluster/raft/fsm.go:applyRegisterFile`) accepts attacker-chosen file paths in manifest-registration proposals without validating them against the configured storage backend. The only check is that the path is non-empty. There is no parent-traversal (`..`) rejection, no allowlist of legitimate prefixes, no scheme restriction (`s3://` vs local), and no length bound. This is fixed in 2026.06.1. Some workarounds are available. Restrict cluster network access to known-trusted peers via strict firewall rules, audit the cluster manifest for unexpected paths (any path not matching the configured storage backend root is suspect), and/or disable cluster mode until the fix is available.","publishedAt":"2026-08-21T23:16:25","lastModifiedAt":"2026-08-24T19:16:38","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-48105","cvssScore":8.3,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:H/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00169,"riskScore":0.84,"affectedProduct":"Arc","affectedVersions":"<26.06.1","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-48105","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-48105","en":"https://www.redsauce.net/en/cves/CVE-2026-48105","fr":"https://www.redsauce.net/fr/cves/CVE-2026-48105","pt":"https://www.redsauce.net/pt/cves/CVE-2026-48105","de":"https://www.redsauce.net/de/cves/CVE-2026-48105","sk":"https://www.redsauce.net/sk/cves/CVE-2026-48105","el":"https://www.redsauce.net/el/cves/CVE-2026-48105"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-48105"}}
