CVE-2026-40394

Varnish Cache 9 before 9.0.1 and Varnish Enterprise before 6.0.16r11 are affected by a workspace overflow during HTTP/2 session upgrade. The vulnerability arises when the HTTP/2 upgrade path repurposes an HTTP/1 request as stream zero and allocates a buffer to reserve space for frames, which can ...

Name of the Vulnerable Software and Affected Versions Varnish Enterprise versions prior to 6.0.16r12 Description Varnish Enterprise versions before 6.0.16r12 are susceptible to a denial of service daemon panic due to a workspace overflow when handling shared VCL. The headerplus.write req0 functio...

CVE-2026-40395: Allocation of Resources Without Limits or Throttling

Varnish Enterprise before 6.0.16r12 allows a "workspace overflow" denial of service daemon panic for shared VCL. The headerplus.writereq0 function from vmodheaderplus updates the underlying req0, which is normally the original read-only request from which req is derived readable and writable from...

CVE-2026-40394: Always-Incorrect Control Flow Implementation

Varnish Cache 9 before 9.0.1 and Varnish Enterprise before 6.0.16r11 allows a "workspace overflow" denial of service daemon panic for certain amounts of prefetched data. The setup of an HTTP/2 session starts with a speculative HTTP/1 transport, and upon upgrading to h2 the HTTP/1 request is...

CVE-2026-40396: Always-Incorrect Control Flow Implementation

Varnish Cache 9 before 9.0.1 allows a "workspace overflow" denial of service daemon panic after timeoutlinger. A malicious client could send an HTTP/1 request, wait long enough until the session releases its worker thread timeoutlinger and resume traffic before the session is closed timeoutidle...

Name of the Vulnerable Software and Affected Versions Varnish Cache versions prior to 9.0.1 Description Varnish Cache 9 before 9.0.1 is susceptible to a denial of service due to a workspace overflow, potentially leading to a daemon panic. A malicious client can exploit this by sending an HTTP/1...

GHSA-VW86-C94W-V3X4 SiYuan: Publish Reader Path Traversal Delete via `removeUnusedAttributeView`

Summary The endpoint /api/av/removeUnusedAttributeView is vulnerable to a path traversal CWE-22 that allows an attacker to delete arbitrary .json files on the server. The issue arises because user-controlled input id is directly used in filesystem path construction without validation or...

Directory Traversal

Overview praisonaiagents is a Praison AI agents for completing complex tasks with Self Reflection Agents Affected versions of this package are vulnerable to Directory Traversal via the listfiles function when the pattern parameter is not properly validated before being passed to Path.glob. An...

GHSA-7J2F-XC8P-FJMQ PraisonAIAgents: Path Traversal via Unvalidated Glob Pattern in list_files Bypasses Workspace Boundary

Summary The 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 i...
