Prior to 0.9.1, both Telegram upload sites in `internal/telegram/bot.go` concatenate the attacker-controlled document filename into a destination path without sanitization, and `path.Join` collapses parent-directory traversal. A remote Telegram user who can message the bot can therefore write outside `uploads/` within the persistent agent workspace mounted at `/workspace/agent`. Because `allow_from: []` permits all senders by default, no prior authentication or privilege is required in that configuration. The attacker can plant or overwrite `CLAUDE.md`, instruction, skill, hook, or configuration files that the Claude agent reads and operates on across later runs, turning a document upload into stored instruction injection. The demonstrated arbitrary-write scope is the persistent agent workspace volume, not an unrestricted host-filesystem write. This issue is fixed in version 0.9.1."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"mtzanidakis","product":"praktor","versions":[{"version":"< 0.9.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","baseScore":8.2,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":4.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-30T19:45:09.898798Z","id":"CVE-2026-62331","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-22"}]}],"references":[{"url":"https://github.com/mtzanidakis/praktor/commit/c3731eeda01c0b3ec1dbd13cccd5a147c3182141","source":"security-advisories@github.com"},{"url":"https://github.com/mtzanidakis/praktor/pull/228","source":"security-advisories@github.com"},{"url":"https://github.com/mtzanidakis/praktor/releases/tag/v0.9.1","source":"security-advisories@github.com"},{"url":"https://github.com/mtzanidakis/praktor/security/advisories/GHSA-48v2-6jcm-fc99","source":"security-advisories@github.com"}]}}]}
