CVSS v3.1 |
| A flaw was found in Keycloak. An authenticated administrator with the `manage-clients` role can exploit a Time-of-check to time-of-use (TOCTOU) vulnerability in the name-based admin role checks. This allows the attacker to escalate their privileges to `realm-admin` for all users within the realm, granting them extensive control over the system. The composite role relationship persists even after the attacker's own permissions are revoked and across system reboots. |
| In Eclipse Ankaios versions 0.1.0 through 1.0.2, the agent creates workload files and Control Interface named pipes (FIFOs) under a predictable path derived from the agent name and a hash of the workload's runtime configuration. If a directory or FIFO already exists at that path when the agent (re)starts, the agent reuses it based only on an existence and/or file-type check, without validating its owner or permissions. A local, unprivileged user with write access to the same base directory (by default under `$TMPDIR/ankaios`, e.g. shared `/tmp`) can pre-create this path hierarchy, including the two Control Interface FIFOs, before the agent starts. The agent then treats the attacker-owned FIFOs as the legitimate Control Interface for the targeted workload. The attacker can complete the Control Interface handshake and issue requests using that workload's configured `controlInterfaceAccess` permissions, allowing impersonation of the workload and, depending on its configured permissions, unauthorized reading and/or modification of the cluster's desired state. |
| A race condition in the ZPA tunnel handler of affected versions of Zscaler Client Connector (ZCC) allows a heap corruption, resulting in a denial of service (client crash) and potentially arbitrary code execution in the context of the ZCC process. |

| Description
When launching a Docker or OCI worker, the setuid-root `worker-launcher` first changes ownership of the
entire worker directory to the untrusted topology user, and only afterwards reads and acts on the command
file that the supervisor wrote into that same directory. The file is opened without `O_NOFOLLOW` and without
re-verifying its owner, so between the ownership change and the read the tenant can replace its contents.
For the Docker path the parsed command is executed with real uid 0, and the command sanitiser is not a
privilege boundary: it admits `-v` with an arbitrary source, `--device`, `--cap-add`, `--security-opt`,
`--user` and `--net`, and copies positional arguments through verbatim. A rewritten file therefore yields an
attacker-authored, root-equivalent container invocation with the host filesystem available.
For the OCI path the same rewrite window applies, and mount validation is structural only, with no
source or destination allow-list, so arbitrary host paths can be bind-mounted read-write into the
container. The `username` field of the command file is likewise attacker-settable and is checked only
against non-root and minimum-uid rules, permitting execution as another tenant's uid.
Mitigation
Upgrade to 3.1.0, where the command file is validated before the ownership change and re-verified on open,
and where mount sources and destinations are constrained by configuration.
Users who cannot upgrade immediately should disable Docker and OCI worker isolation, or restrict topology
submission on affected supervisors to trusted principals. Note that the launcher must be rebuilt and
reinstalled after upgrading.

| Description
The setuid-root `worker-launcher` binary adjusts ownership and permissions of worker directories by walking
the tree with FTS and calling `lchown` and `chmod` on each entry's full pathname while running with an
effective uid of 0. Both syscalls re-resolve the path at the time of the call, after FTS has classified the
entry, and the trees being walked are owned and writable by the untrusted topology user.
A tenant running code on a supervisor node could therefore replace an intermediate directory component with
a symbolic link between classification and the privileged operation, redirecting the root-owned `lchown` or
`chmod` at an arbitrary file on the host. The operation is repeatable at will, since crashing a worker
forces a relaunch and blob updates re-run the walk, so a failed attempt costs the attacker nothing.
This crosses the boundary that `supervisor.run.worker.as.user` and container isolation are intended to
enforce. It is the same defect class as the Hadoop container-executor issues from which this code derives.
Mitigation
Upgrade to 3.1.0, where the privileged walk operates on file descriptors it has already stat'd rather than
on pathnames re-resolved at call time.
Users who cannot upgrade immediately should not run untrusted topology code on supervisors configured with
`supervisor.run.worker.as.user`, since the launcher is the boundary being crossed. Note that the launcher
must be rebuilt and reinstalled after upgrading; replacing the Java artifacts alone is not sufficient.

| Yealink SIP-T33G firmware versions 124.86.x.x prior to 124.87.0.0 contain a race condition vulnerability that allows authenticated attackers to interrupt active diagnostic processes by concurrently deleting output files written to predictable paths under the diagnostic directory. Attackers can trigger a diagnostic operation such as traceroute or ping and simultaneously invoke the file deletion endpoint to terminate the running process, leaving the system in an inconsistent state. |
| A vulnerability was found in vvbbnn00 WARP-Clash-API up to c7bf2360073959861219b422e51ae86411051b46. This affects the function doUpdateLicenseKey. The manipulation results in race condition. The attack can be launched remotely. The attack requires a high level of complexity. The exploitability is reported as difficult. The exploit has been made public and could be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer. |
| Hoverfly is an open source API simulation tool. Prior to version 1.12.8, when Hoverfly is running in Diff mode, the `AddDiff()` function writes to the shared `responsesDiff` map without any synchronization (no mutex). When multiple proxy requests are processed concurrently (the normal case for any proxy), the concurrent map writes trigger Go's built-in race detector which causes a `fatal error: concurrent map read and map write`, immediately killing the entire Hoverfly process. This is trivially exploitable by sending multiple simultaneous requests. Version 1.12.8 patches the issue. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to obtain sensitive information due to a race condition during the WebSocket handshake process. |
| In FRRouting FRR before 8.5, the service user (usually frr) can escalate its privileges to root by monitoring the configuration directory (/etc/frr) and replacing config files upon creation with, for example, symlinks to change the ownership of arbitrary files. This is a TOCTOU Race Condition caused by a combination of touch and chown. |
| Time-of-check time-of-use (toctou) race condition in Windows Kernel allows an authorized attacker to elevate privileges locally. |
| ContextForge is an AI gateway, registry, and proxy that provides centralized discovery, guardrails, and management for MCP, A2A, and REST or gRPC APIs. Prior to 1.0.3, the /admin/gateways/test call site in mcpgateway/admin.py calls validate_gateway_test_url() in mcpgateway/common/validators.py to resolve and reject private, loopback, link-local, and cloud-metadata addresses, but ResilientHttpClient later resolves the original hostname again without binding the validated address. When MCPGATEWAY_ADMIN_API_ENABLED is enabled, an attacker with a database-backed role containing explicit gateways.read permission can use DNS rebinding to return a public address during validation and a private or metadata address during connection, bypassing ssrf_blocked_networks and ssrf_dns_fail_closed because those controls apply only to the validation-time result. The endpoint's allow_admin_bypass=False setting means a bootstrap-only virtual platform-admin identity without a database role is not sufficient. Successful exploitation can reach internal services and cloud metadata, expose cloud credentials, access internal APIs, or probe internal network ports. This issue is fixed in version 1.0.3. |
| Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to denial of service. |

| An issue in the Leptonica linked library (v1.79.0) allows attackers to cause an arithmetic exception leading to a Denial of Service (DoS) via a crafted JPEG file. |
| In the Linux kernel, the following vulnerability has been resolved:
mm: memcg: stop reclaim when a limit update is superseded
kernfs serializes file operations only per open file, so separate open
files can update the same memory.high or memory.max file concurrently.
Both handlers store the new limit before synchronous reclaim, but continue
to use the writer's local target in the reclaim loop. If another writer
raises or removes the limit, the first writer can continue reclaiming
toward a stale target.
For memory.max, this can leave the writer looping indefinitely once
reclaim retries are exhausted. The OOM path sees sufficient margin under
the current limit and returns true without killing, while the writer still
compares usage against its stale target and records another OOM event.
Check the current limit at the start of each reclaim iteration and stop if
it no longer matches the writer's target.
Reproducer:
Populate a cgroup with anonymous memory and disable swapping. Lower
memory.max from one open file, then restore it to "max" through another
open file after the new limit becomes visible.
Without the patch, the first writer remains blocked and repeatedly
increments the OOM event counter. With the patch, it returns normally.
This was not motivated by a reported production workload. We found it
through automated randomized testing for our cgroup observability work
and reduced it to the reproducer above. |
