Spring Authorization Server's default consent page renders user-controlled values without HTML entity encoding.

Spring Authorization Server's default consent page renders user-controlled values without HTML entity encoding. When using the DefaultConsentPage, an attacker can craft an OAuth2 authorization request containing a malicious value that is stored server-side and later rendered unencoded in the default consent page presented to the end user.

CVE-2026-59284
Arbitrary property key injection via writable /actuator/env in Spring Cloud Commons

Spring Cloud Commons does not apply an allow list to property keys written through the writable Spring Boot /actuator/env endpoint, so nothing prevents arbitrary keys from being set. The flaw is triggered when write support on /actuator/env is enabled and a request with attacker-chosen property keys is submitted by an actor with high privileges on the application (CVSS PR:H), or by anyone who can reach the endpoint if it is left insufficiently protected. Because injected keys can modify arbitrary configuration properties, the attacker can alter application behavior beyond the component's normal scope (CVSS scope changed), yielding a high integrity impact and a limited availability impact with no confidentiality loss. Anyone running Spring Cloud Commons 3.1.10 and earlier, 4.0.0–4.2.6, 4.3.0–4.3.3, or 5.0.0–5.0.2 with the writable env endpoint enabled is affected. No exploitation is known: it is not in CISA KEV, no public proof-of-concept exists, and EPSS is about 0.3%.

Do: Upgrade Spring Cloud Commons to a patched release beyond the affected range for your line (latest 5.0.x, 4.3.x, 4.2.x/4.0.x, or 3.1.x patch per the Broadcom advisory). Until patched, disable writes to /actuator/env (e.g., management.endpoint.env.post.enabled=false) or restrict the endpoint to trusted, highly privileged users and keep actuator endpoints off the public internet. Audit which services enable the writable env endpoint and who can reach it.

Applications that deserialize execution contexts with Jackson2ExecutionContextStringSerializer are vulnerable to a deserialization attack if they use an untrusted data source for the job repository. The JobParameterDeserializer does not properly enforce the trusted-types allowlist, allowing an attacker to craft malicious input that can lead to arbitrary code execution, including known Jackson RCE gadgets.

CVE-2026-59310
Unauthenticated Path Traversal RCE in Broadcom VMware vCenter Server Syslog

CVE-2026-59310 is a directory traversal (CWE-22) vulnerability in the Syslog server component of VMware vCenter Server, rated critical at CVSS 9.8. It can be triggered over the network without authentication or user interaction, allowing a malicious actor with network access to vCenter to achieve arbitrary code execution. An attacker who exploits it gains code execution on the vCenter appliance, and reported campaigns show it has been used to establish persistent remote access and, by a suspected China-nexus actor, to deploy Babuk ransomware. Any organization running an affected version of vCenter Server is exposed, especially where the management interface is reachable from the internet; the available data does not specify affected version ranges. Exploitation is confirmed in the wild: CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-08-18, it was reportedly exploited just five days after disclosure, and EPSS estimates a 45.9% probability of exploitation within 30 days (99th percentile).

Do: Upgrade vCenter Server to the patched release identified in Broadcom's advisory (no specific version ranges are provided in this data) and prioritize any vCenter that is internet-facing, in line with CISA KEV and BOD 26-04 requirements for federal agencies. Until patched, restrict access to the vCenter management interface to trusted networks and verify whether the vCenter Syslog server is enabled. Hunt for compromise indicators, including unexplained remote-access persistence and Babuk ransomware artifacts, given the documented China-nexus exploitation.

RabbitMQ is a messaging and streaming broker. Prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6, AMQP 0-9-1, AMQP 1.0, and Stream Protocol authentication can allow a loopback-restricted user such as guest to connect remotely when traffic is accepted through a trusted PROXY-protocol path and the backend listener is loopback-bound because the loopback check uses the listener-side socket address instead of the real client source. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.
