PYSEC-2026-2949 PraisonAIAgents: Arbitrary File Read via read_skill_file Missing Workspace Boundary and Approval Gate

Summary readskillfile in skilltools.py allows reading arbitrary files from the filesystem by accepting an unrestricted skillpath parameter. Unlike filetools.readfile which enforces workspace boundary confinement, and unlike runskillscript which requires critical-level approval, readskillfile has...

PraisonAIAgents: Path Traversal via Unvalidated Glob Pattern in list_files Bypasses Workspace Boundary

SummaryThe listfiles tool in FileTools validates the directory parameter against workspace boundaries via validatepath, but passes the pattern parameter directly to Path.glob without any validation. Since Python's Path.glob supports .. path segments, an attacker can use relative path traversal in...

Summary Type: Authorization bypass enabling owner lockout. The DELETE /workspaces/workspace id/members/user id endpoint is gated only by require workspace memberworkspace id default min role="member". Any member can remove any other member, including the workspace owner, using a single DELETE...

PT-2026-59562

Summary PraisonAI Platform's workspace-scoped REST routes contain a systemic object-level authorization flaw that allows an authenticated user from one workspace to access, modify, and delete objects belonging to another workspace by supplying the victim object's global UUID. The affected pattern...

PT-2026-59567

Summary The PraisonAI Platform API has two authorization failures that together break workspace isolation. The service layer for issues and projects performs global primary-key lookups without checking workspace ownership, so any authenticated user can read, modify, and delete resources in any...

Summary When setting model permissions so that a group has read access to it, intending for other users to use it, those users also can read the model's system prompt. However users may consider their system prompt confidential, so we consider this a security issue. Compare...

CVE-2026-26396

OpenBMB XAgent v1.0.0 and before is vulnerable to path traversal in the file function in XAgent/XAgentServer/application/routers/workspace.py. The input parameter “filename” is user-controllable and is concatenated into the file path to be read without proper validation, leading to a directory...
