asyncssh has an incomplete fix for CVE-2026-45309 — AuthorizedKeysFile %u still escapes the intended directory via a leading ~ (and weakly via ${ENV}) username substitution

Incomplete fix for CVE-2026-45309 GHSA-g794-3fmp-753h. The 2.23.0 guard that sanitises the SSH username before %u substitution in AuthorizedKeysFile blocks /, \ and .., but does not block a leading or $ENV, both of which are re-introduced by later expansion and reach the file open — defeating the...

Cloudreve WebDAV (`/dav`) has Path Traversal / Broken Access Control — scoped DAV credential escapes its configured account root

Summary A Cloudreve WebDAV account stores a uri that defines the account's root folder. The WebDAV request handler stripPrefix in pkg/webdav/webdav.go trims the /dav prefix from the request path and joins the remainder to that root with fs.URI.JoinRaw, but never checks that the joined URI stays...

OpenWISP IPAM has broken object-level authorization: ExportSubnetView lets a member of one organization export another organization's subnet and all its IP addresses

Summary OpenWISP IPAM is multi-tenant: every Subnet belongs to an organization, and API access is scoped to the organizations a user belongs to. The CSV export endpoint, ExportSubnetView, omits the organization-membership check that its import sibling performs, and loads the subnet by primary key...

Trojanized pantheon-agents 0.6.1 and 0.6.2 on PyPI ship a credential stealer (supply-chain account compromise)

Summary The PyPI account that publishes pantheon-agents was compromised in the June 2026 "Hades" PyPI supply-chain attack Mini Shai-Hulud / Miasma lineage.
