Descripción técnica

Wazuh 4.0.0 before 4.14.7 and 5.0.0-beta2 contain a denial of service vulnerability that allows authenticated attackers with allow_run_as enabled to exhaust CPU resources by submitting arbitrarily deeply nested JSON structures to the POST /security/user/authenticate/run_as endpoint. Attackers can repeatedly submit malformed auth_context bodies with unlimited nesting depth to cause the API framework to consume excessive CPU, denying service to all other API consumers.

———jsoup through 1.23.2, fixed in commit 862ba2f, contains an uncontrolled resource consumption vulnerability in XmlTreeBuilder that allows remote attackers to exhaust JVM heap memory by supplying a deeply nested XML document with uniquely-namespaced elements. The builder copies the entire inherited namespace map on every start element, causing quadratic time and memory complexity, which attackers can exploit to trigger an OutOfMemoryError and terminate the application.4h CVE-2026-77082—

———n8n before 1.123.69, 2.x before 2.33.4, and 2.34.x before 2.34.1 contains a regular expression denial of service (ReDoS) vulnerability in the Filter and Switch nodes, which compile user-supplied regex patterns with new RegExp() and execute them synchronously on the worker thread without complexity validation or execution timeout. A crafted regex pattern can block the worker for an extended period per data item processed, delaying other workflow executions on the same worker.9h CVE-2026-731987.5 ALT

—

——0A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the `/ipa/i18n_messages` endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial of service (DoS) condition.5h CVE-2026-731977.5 ALT

—

——0A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service.8h CVE-2026-731964.3 MED

—

——0A flaw was found in FreeIPA. A low-privilege authenticated user can exploit this vulnerability by submitting an oversized One-Time Password (OTP) key value. This oversized key is then decoded and re-encoded without proper size limits, consuming excessive CPU and memory resources. This can lead to a denial of service, degrading the availability of the IPA service.5h CVE-2026-145146.5 MED
