High [CVE-2026-54499] Remote Code Execution via unsafe deserialization in model loaders
Stanza is a Stanford NLP Python library for tokenization, sentence segmentation, NER, and parsing of many human languages. Prior to 1.12.2, Stanza model loaders such as stanza.models.common.pretrain. Pretrain.load() attempt torch.load(..., weights_only=True) but fall back to torch.load(..., weights_only=False) on attacker-controllable pickle. UnpicklingError, allowing a malicious.pt pretrain or model file to execute arbitrary pickle code when a Stanza NLP pipeline loads it. This issue is fixed in version 1.12.2. However, if this safe load fails due to an attacker-controllable pickle. UnpicklingError, the loaders fall back to an unsafe deserialization method. This allows a remote attacker to craft a malicious pretrain or model file that, when loaded by a Stanza NLP pipeline, can execute arbitrary code with the privileges of the affected process, leading to potential credential theft or data exfiltration. An unsafe deserialization vulnerability in the Stanza Python library can lead to remote code execution. A malicious model pretrain file from an untrusted or compromised source can trigger an insecure deserialization fallback during model loading, resulting in arbitrary code execution with the privileges of the affected process. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-502.
High [CVE-2026-55471] XML External Entity injection allows local file disclosure and SSRF
HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.10, org.hl7.fhir.utilities. XsltUtilities saxonTransform(...) overloads instantiated a bare net.sf.saxon. TransformerFactoryImpl() without ACCESS_EXTERNAL_DTD or ACCESS_EXTERNAL_STYLESHEET restrictions, allowing an attacker who controls or can tamper with transformed XML to trigger XML External Entity injection for local file disclosure and blind XXE or SSRF to arbitrary URLs reachable from the host. This issue is fixed in version 6.9.10. A flaw was found in the HAPI FHIR `XsltUtilities` component. The `saxonTransform` functions within this utility do not adequately restrict external entity access when processing XML. Successful exploitation can lead to local file disclosure, enabling the attacker to read sensitive files from the system. Additionally, it can result in Server-Side Request Forgery (SSRF), where the attacker can force the system to make requests to arbitrary network resources, potentially exposing internal network information or cloud metadata. An unauthenticated, remote attacker can exploit this by providing specially crafted XML data to disclose local files or perform Server-Side Request Forgery (SSRF).
High [CVE-2026-55470] ca.uhn.hapi.fhir/org.hl7.fhir.validation.cli: HAPI FHIR: Denial of Service via Regular Expression Backtracking in DSTU2 Module
HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.10, the fix for CVE-2026-45367 incompletely patched the DSTU2 module, leaving FHIRPathEngine.matches() in org.hl7.fhir.dstu2/utils/FHIRPathEngine.java to call raw String.matches(sw) without RegexTimeout protection while replaceMatches() was updated, allowing an unauthenticated attacker to trigger catastrophic regex backtracking and exhaust server CPU. This issue is fixed in version 6.9.10. Specifically, the FHIRPathEngine.matches() function in org.hl7.fhir.dstu2 did not include protection against regular expression timeouts. This allows an unauthenticated attacker to submit a specially crafted FHIRPath expression, triggering catastrophic regular expression (regex) backtracking. The consequence is a Regular Expression Denial of Service (ReDoS), which can exhaust server CPU resources and lead to service disruption. This flaw is rated as Important because an unauthenticated, remote attacker can exploit an incomplete patch in the HAPI FHIR DSTU2 module. By submitting a specially crafted FHIRPath expression, an attacker can trigger a Regular Expression Denial of Service (ReDoS) attack, leading to significant resource exhaustion and service unavailability on affected systems. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
High [CVE-2026-13320] Arbitrary script execution via improper input sanitization
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 15.7 before 18.11.7, 19.0 before 19.0.4, and 19.1 before 19.1.2 that under certain conditions could have allowed an authenticated user to execute arbitrary scripts in another user's browser session due to improper sanitization of user-supplied input. A flaw was found in GitLab. This vulnerability allows for the execution of arbitrary scripts within another user's browser session, commonly known as Cross-Site Scripting (XSS). This could lead to unauthorized actions or information disclosure. Red Hat severity: Important — CVSS 7.3 (CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:N). Weakness: CWE-79. Red Hat lists OpenShift Pipelines; Red Hat OpenShift Container Platform 4 as not affected.
High [CVE-2026-54591] Arbitrary file write via path traversal in SCP client
AsyncSSH is a Python package which provides an asynchronous client and server implementation of the SSHv2 protocol on top of the Python asyncio framework. Prior to 2.23.1, a malicious SSH server can write arbitrary files on the asyncssh SCP client's filesystem by sending filenames containing../ traversal sequences because _parse_cd_args in scp.py returns server-provided names verbatim and _recv_files joins them to the destination path without enforcing the target directory boundary. This issue is fixed in version 2.23.1. This could allow the server to write arbitrary files to the client's filesystem, leading to unauthorized data modification or system disruption. Red Hat severity: Important — CVSS 8.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H). Weakness: CWE-22.
High [CVE-2026-58250] Denial of Service via repeated leafnode INFO messages during pre-authentication
NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.12.8 and 2.11.17, an unauthenticated peer with network access to a leafnode listener with compression enabled could crash the server during the pre-authentication leafnode handshake by sending repeated leafnode INFO protocol messages before authentication and account setup completed. This issue is fixed in versions 2.12.8 and 2.11.17. This leads to a Denial of Service (DoS), making the server unavailable to legitimate users. This is an Important denial of service vulnerability in NATS Server. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-476. Red Hat lists Red Hat Hardened Images as not affected.
High [CVE-2026-58253] Authentication bypass and privilege escalation via parser fast path
NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.0, 2.12.7, and 2.11.16, when no_auth_user was configured, a parser fast path intended for ordinary client connections could also apply to route or leafnode listeners, allowing an unauthenticated peer to bypass inter-server CONNECT authentication and operate with the privileges associated with that connection type. This issue is fixed in versions 2.14.0, 2.12.7, and 2.11.16. A flaw was found in NATS Server. This allows an unauthenticated attacker on an adjacent network to bypass inter-server authentication. Consequently, the attacker can operate with the privileges of a trusted connection, leading to a high impact on data integrity. Red Hat severity: Important — CVSS 8.8 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:L/I:H/A:L). Weakness: CWE-551. Red Hat lists Red Hat Hardened Images as not affected.
