Medium [CVE-2026-75838] Cross-Site Scripting via IN_PLACE sanitization
DOMPurify before 3.4.13 contains a cross-site scripting vulnerability in IN_PLACE sanitization where element-removal hooks fail to neutralize detached subtrees. Attackers can supply HTML with event handlers on descendant elements that execute after sanitization completes, even though the returned root appears clean. A flaw was found in DOMPurify. A remote attacker can exploit this by supplying specially crafted HTML with event handlers. This allows the execution of malicious scripts even after the HTML appears to be sanitized, leading to potential information disclosure or unauthorized actions. This cross-site scripting flaw in DOMPurify affects Red Hat products that utilize the library for HTML sanitization. The vulnerability allows attackers to execute arbitrary JavaScript by exploiting incomplete neutralization of detached subtrees during IN_PLACE sanitization, but only when a non-default configuration involving an element-removal hook is in use and user interaction with specially crafted content occurs. Red Hat severity: Moderate — CVSS 6.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N). Weakness: CWE-79. Affected products named by the advisory: Red Hat Ansible Automation Platform 2.6 for RHEL 9; Red Hat Advanced Cluster Security for Kubernetes 4.10; Red Hat Advanced Cluster Security for Kubernetes 4.11; Red Hat Ansible Automation Platform 2.1; and 29 more.
Medium [CVE-2026-19608] Name-only group claims let same-name groups satisfy path-specific group policies
A flaw was found in the group policy provider of Keycloak authorization services, which is used to manage fine-grained access control to resources. The issue occurs when the system evaluates group-based policies using tokens that only contain group names rather than full paths. If two groups in different parts of the organization share the same name, a user in the unauthorized group can be mistaken for a member of the authorized group. This can allow a user to gain unauthorized access to protected resources they should not be able to reach. The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate, given that exploitation requires a specific configuration where OIDC group mappers emit name-only claims and a group name collision exists across different paths. The vulnerability's root cause is the group policy provider's fallback to matching bare group names when full path information is missing from the token claims. Weakness: CWE-285. Affected Red Hat products: Red Hat Build of Keycloak. Red Hat lists Red Hat Single Sign-On 7 as not affected. Red Hat does not currently list a fixing RHSA for this CVE.

Medium [CVE-2026-73560] Server-Side Request Forgery and arbitrary file read via improper media processing
vLLM is an inference and serving engine for large language models. Prior to 0.26.0, the MiMoV2OmniMultiModalProcessor in vllm/transformers_utils/processors/mimo_v2_omni.py passes attacker-controlled image and audio strings through _fetch_image, requests.get, and Image.open instead of MediaConnector, bypassing allowed_media_domains and allowed_local_media_path protections and allowing server-side requests and reads of arbitrary files accessible to the vLLM process. This issue is fixed in version 0.26.0. This vulnerability allows a remote attacker to perform Server-Side Request Forgery (SSRF) and read arbitrary local files accessible to the vLLM process. Successful exploitation could lead to unauthorized access to internal network resources, cloud metadata, and sensitive local system files. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-918.

Medium [CVE-2026-71486] Denial of Service via unbounded token ID decoding
vLLM is an inference and serving engine for large language models. Prior to 0.26.0, the /v1/completions/derender and /v1/chat/completions/derender endpoints accept caller-supplied GenerateResponse objects whose generate_responses, choices, token_ids, prompt_logprobs, logprobs.content, top_logprobs, and routed_experts structures are processed by OnlineDerenderer and tokenizer.decode before max_model_len, max_tokens, max_num_seqs, or response-size limits are enforced, allowing an authenticated API client to consume excessive CPU and memory and produce oversized responses. This issue is fixed in version 0.26.0. A flaw was found in vLLM. These endpoints process the objects without enforcing output bounds or response-size limits. This can lead to excessive consumption of CPU and memory resources, resulting in a Denial of Service (DoS). Red Hat severity: Moderate — CVSS 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-770. Affected Red Hat products: Red Hat AI Inference Server; Red Hat Enterprise Linux AI (RHEL AI) 3; Red Hat OpenShift AI (RHOAI). Red Hat does not currently list a fixing RHSA for this CVE.
Medium [CVE-2026-59903] Information disclosure via CORS Vary header overwrite
Netty is an asynchronous, event-driven network application framework. Prior to 4.1.137.Final and 4.2.17.Final, io.netty.handler.codec.http.cors. CorsHandler setVaryHeader replaces application Vary headers such as Authorization or Cookie with Origin, allowing a caching proxy or CDN to reuse authenticated responses across users and disclose sensitive information. This Moderate impact information disclosure flaw in Netty arises from the `CorsHandler` incorrectly overwriting application `Vary` headers with `Origin`. This could allow caching proxies or CDNs to reuse authenticated responses across different users, potentially exposing sensitive data. Exploitation requires the presence of a caching proxy or CDN in front of the affected Netty application. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N).
