  1. CVE-2026-54637 5.5 Moyenne

    dragonflyoss dragonfly

    Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.4.4-rc.3, the scheduler's default unauthenticated v1 gRPC flow accepts attacker-controlled PeerHost.Ip and PeerHost.DownPort values through RegisterPeerTask and ReportPeerResult, storeHost copies those values into resource.Host, and handlePeerSuccess invokes Peer.DownloadTinyFile() for a TINY task. DownloadTinyFile() in scheduler/resource/standard/peer.go builds an HTTP GET request from the supplied address without destination validation, allowing a remote attacker to probe loopback, link-local, and private services and place up to TinyFileSize, 128 bytes, of a response in Task.DirectPiece for later retrieval. PeerHost.DownPort is restricted to ports 1024 through 65534, and the issue provides read SSRF rather than remote code execution. The remediation blocks loopback and link-local targets, while RFC1918 destinations remain reachable because IsGlobalUnicast accepts private ranges. This issue is fixed in 2.4.4-rc.3.

  2. CVE-2026-49254 2.9 Faible

    dragonflyoss dragonfly

    Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.4.4, manager/router/router.go registers GET /api/v1/oauth and GET /api/v1/oauth/:id without jwt.MiddlewareFunc() or RBAC(), while manager/handlers/oauth.go returns models.Oauth records and manager/models/oauth.go exposes Oauth.ClientSecret as client_secret in JSON. When an administrator has configured a GitHub or Google OAuth provider, an unauthenticated network client can reach GetOauth or GetOauths, load the stored models.Oauth record, and obtain the provider's client secret, client identifier, and redirect URL. The earlier GHSA-j8hf-cp34-g4j7 remediation protected the /jobs group only and did not protect these OAuth GET handlers. Disclosure of client_secret can enable abuse of the configured identity-provider integration, subject to the provider's redirect URI restrictions. This issue is fixed in 2.4.4.

  3. CVE-2026-80899 – Non évaluée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: erofs: remove fscache backend entirely EROFS over fscache was introduced to provide image lazy pulling functionality. After the feature landed, the fscache subsystem made netfs a new hard dependency, which is unexpected for a local filesystem and has an kernel-defined caching hierarchy which could be inflexible compared to the fanotify pre-content hooks. Therefore, this feature has been deprecated for almost two years. As EROFS file-backed mounts and fanotify pre-content hooks both upstream for a while and already providing equivalent functionality (erofs-utils has supported fanotify pre-content hooks), let's remove the fscache backend now. The main application of this feature is Nydus [1], and they plan to move to use fanotify pre-content hooks in the near future too. I hope this patch can be merged into Linux 7.2, which is also motivated by newly found implementation issues [2][3] that are not worth investigating given the deprecation and limited development resources. The associated fscache/cachefiles cleanup patch will follow separately through the vfs tree (netfs) later: it seems fine since the codebase is isolated by CONFIG_CACHEFILES_ONDEMAND.
