Red Hat Openshift Dev Spaces

Unauthenticated path traversal in gvproxy, the network forwarder shipped in the gvisor-tap-vsock package (used by Podman Desktop, Red Hat OpenShift/CRC tooling and related Red Hat products), lets an attacker who can reach the /services/forwarder/expose control endpoint supply an arbitrary socket path that is passed unsanitised to os.Remove, resulting in deletion of arbitrary files on the host. The defect is reachable without credentials (PR:N) but requires adjacent/guest-side network access to the forwarder API (AV:A), which is normally bound to the virtual network rather than exposed as a routed internet service; impact is limited to integrity and availability (no data disclosure). No public exploit code has been identified at time of analysis and the flaw is not listed as confirmed actively exploited (CISA KEV); an upstream fix exists in gvisor-tap-vsock PR #718. The vendor score of 9.3 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H) reflects low-complexity, unauthenticated access combined with a scope change and High integrity/availability impact, and the actual risk depends heavily on whether the forwarder control API is reachable by an untrusted guest or adjacent host.
Unauthenticated remote connection flooding against the cockpit-tls front-end of Cockpit (the TLS terminator for the Cockpit web console, default TCP 9090) forces the service to spawn an unbounded number of detached threads, exhausting memory and file descriptors until the console degrades or becomes unavailable. The flaw, tracked as CWE-770 (allocation of resources without limits or throttling), carries a 7.5 CVSS score (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and affects Cockpit as shipped in Red Hat Enterprise Linux 7, 8, 9, and 10 as well as Red Hat OpenShift Dev Spaces; the CVSS vector confirms the attack needs no authentication or user interaction. Exploitation is bounded to availability of the management console rather than the underlying host services, CISA's SSVC assessment records Exploitation: none (automatable: yes, technical impact: partial), and no public exploit code was identified at time of analysis. Because the primitive is simply 'open many concurrent TCP connections,' it is highly automatable and becomes a practical risk anywhere port 9090 is reachable from an untrusted network.
Quarkus HTTP security path-normalization discrepancy allows unauthenticated remote attackers to craft a URL that the security matcher treats as public while the dispatcher routes it to a protected endpoint, bypassing path-based authorization and reading sensitive data (CVSS 3.1 7.5, C:H/I:N/A:N). This affects deployments that rely on Quarkus HTTP security path-pattern policies to gate confidential endpoints; applications using only handler-level role or annotation checks are not bypassed this way. No public exploit identified at time of analysis.
Memory exhaustion denial of service in cockpit-ws affects Red Hat Enterprise Linux 7 through 10 and Red Hat OpenShift Dev Spaces, exploitable by any remote unauthenticated attacker. The login page request handler leaks a heap allocation on every HTTP request that includes a CockpitLang cookie, with no authentication or special privilege required. Sustained request flooding with this cookie will exhaust host memory, crashing the cockpit-ws service and potentially destabilizing the underlying host; no public exploit or active exploitation has been identified at time of analysis.
Arbitrary VS Code command execution in the Red Hat vscode-java extension allows a malicious Java source file to embed hidden commands inside JavaDoc hover Markdown, so that a developer who simply clicks a crafted link in a hover popup triggers attacker-chosen commands that can escalate to full system compromise in trusted workspaces. The flaw stems from the extension rendering JavaDoc hovers as fully-trusted Markdown, and it also affects Red Hat OpenShift Dev Spaces, which bundles the extension. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the network reach combined with only a single click of user interaction makes it high-impact.
A file descriptor leak in the containers/storage Go library's archive.ApplyLayer and ApplyUncompressedLayer functions causes descriptors to be left open whenever corrupt or malicious image layers or tar streams are unpacked, and repeated processing of such inputs can exhaust the hosting process's file descriptor limit. The weakness is unauthenticated in CVSS terms (PR:N) but local in scope (AV:L) and requires the victim to actually process attacker-influenced layers (UI:R), so an attacker must first get malformed image content in front of a build, pull, or sync loop. Impact is availability-only and confined to the affected process (C:N/I:N/A:L, S:U): no code execution and no data exposure; a single bad input does not cause denial of service, only sustained repetition does. No public exploit code has been identified at time of analysis and the issue is not in CISA KEV, and EPSS scoring was not supplied with the source data.
An integer-wraparound in Cockpit's do_lastlog() login-accounting routine on ILP32 (32-bit) builds allows a low-privileged but authenticated local user holding an administrator-provisioned abnormally large UID to read and modify other users' lastlog records, producing low confidentiality and low integrity impact (CVSS 3.1 base 3.6, AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N). Exploitation requires a 32-bit build, a deliberately created large-UID account, and local access to the host; 64-bit LP64 builds do not overflow and are unaffected, and no public exploit code has been identified at time of analysis.
Denial of service in Red Hat's cockpit-ws web service lets a remote, unauthenticated attacker crash the process by sending a request to the exact configured WebService.UrlRoot prefix without a trailing slash, taking the Cockpit management interface offline. The flaw is only reachable on installations that have explicitly set the non-default WebService.UrlRoot option; default deployments are unaffected, and impact is availability-only with no data exposure or code execution. There is no public exploit identified at time of analysis, no confirmed active exploitation (not in CISA KEV), and exploitation carries a high-attack-complexity rating (AC:H) because the attacker must know and target the exact URL-root path.
A path-handling flaw in the containers/storage Go library lets a crafted tar archive containing a malicious whiteout entry (for example 'victim/.wh.') cause UnpackLayer, ApplyLayer, or ApplyUncompressedLayer to replace the extraction destination directory with an arbitrary file. Systems that unpack container image layers with this library — notably Red Hat Enterprise Linux 10, Red Hat Ansible Automation Platform 2, OpenShift Container Platform 4, Quay 3, OpenShift Virtualization, Dev Spaces, and Red Hat Hardened Images — are in scope. Exploitation requires the operator or process to unpack an attacker-supplied archive, and the integrity impact is confined to the local extraction target; no public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, consistent with the modest CVSS 3.1 base score of 4.4.
Symlink-based path traversal in the buildah/copier Go package allows a crafted tar archive to create files outside the intended extraction directory when the library is used outside of Buildah by a non-root caller. Buildah's own extraction path applies chroot hardening and is explicitly not affected, so real exposure sits with downstream consumers of the package - including Red Hat Ansible Automation Platform 2 and Red Hat Enterprise Linux 10 in the published CPE data, plus other tagged Red Hat products - that unpack untrusted archives with it. Impact is integrity-only (no confidentiality or availability component in the assessed vector), the victim application must actually process the malicious archive (UI:R), EPSS is low at 0.25% (16th percentile), CISA's SSVC records exploitation as none and automatable as no, and no public exploit code has been identified at time of analysis.
