{"cve":"CVE-2026-56835","nvd":{"published":"2026-10-23T12:18:14.897","modified":"2026-10-23T12:18:15.013","status":"Deferred","description":"PraisonAI is a multi-agent teams system. From version 3.11.0 to before version 4.6.59, PraisonAI's Slack bot applies its configured allowed_users, allowed_channels, and unknown-user pairing policy in the normal Slack message event handler, but not in the adjacent Slack app_mention event handler. A Slack workspace user who can mention the bot in a channel where the Slack app is present can trigger the configured PraisonAI agent even when: the sender is not in BotConfig.allowed_users; the channel is not in BotConfig.allowed_channels; unknown_user_policy=\"deny\" is configured; and the same event content is correctly dropped by the normal message handler. This issue has been patched in version 4.6.59.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","score":8.3},"cwes":["CWE-862","CWE-863"],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-qvpf-j64c-jmhr"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-56835","score":0.00215,"percentile":0.11789,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-qvpf-j64c-jmhr","url":"https://osv.dev/vulnerability/GHSA-qvpf-j64c-jmhr","summary":"PraisonAI Slack app_mention bypasses configured user/channel authorization","modified":"2026-07-23T15:11:23.177465510Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":[">=3.11.0 <4.6.59"],"fixed":["4.6.59"]}]},{"id":"PYSEC-2026-3518","url":"https://osv.dev/vulnerability/PYSEC-2026-3518","summary":"PraisonAI Slack app_mention bypasses configured user/channel authorization","modified":"2026-07-23T15:00:20.841431784Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":[">=3.11.0 <4.6.59"],"fixed":["4.6.59"]}]}],"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).
