Summary
A stack buffer overflow flaw was found in the GStreamer H.265 codec parser library (gst-plugins-bad). This flaw occurs when parsing a buffering period SEI message, where an incorrect loop bound is used, potentially leading to writes beyond the allocated stack memory bounds.
Risk Assessment
This vulnerability can allow a crafted H.265 video file to cause application crashes or potential stack memory corruption, posing a risk to system stability.
Recommendation
It is recommended to update the GStreamer library to the latest version to mitigate this vulnerability and to monitor applications using this codec for potential attacks.

- CVE-2026-109758Critical
Perforce Helix Authentication Service (HAS) versions 2022.1-2025.2 retain a default SCIM bearer token that is not automatically replaced with a random value during installation. An attacker knowing this token can gain unauthorized access to the SCIM API and perform user and group operations. This issue can be chained with CVE-2026-61834, potentially leading to remote code execution.

GitLab CE/EE versions from 19.2 to 19.2.8, 19.3 to 19.3.5, and 19.4 to 19.4.2 contain a vulnerability that, under certain conditions, could allow an unauthenticated user to execute arbitrary code on the GitLab server. The issue stems from insufficient validation of regular expressions in CI/CD configuration.

SAP Cloud SDK for Python contains an OAuth2 SSRF vulnerability affecting multi-tenant BTP applications. An attacker controlling the tenant_subdomain parameter can redirect OAuth2 token requests to an attacker-controlled server, leading to client credential exfiltration.
- CVE-2026-89110Critical
SAP NetWeaver Visual Composer does not perform sufficient authorization checks in certain portal functionality. An attacker with low privileges could invoke internal operations on a preconfigured remote system, which depending on the remote connection configuration could lead to full compromise of the remote system.
- CVE-2026-89108Critical
SAP Manufacturing Integration and Intelligence does not sufficiently enforce authorization boundaries within certain administrative functionality. An attacker with MII administrator privileges could submit a specially crafted request to provision an account with elevated privileges on the underlying Java application server. Successful exploitation could allow the attacker to gain administrative control over the system.
- CVE-2026-89107Critical
SAP S/4HANA (Manage Substitution/Validation Rules) does not sufficiently validate input processed by rule definition functionality that utilizes a domain-specific scripting language. An authenticated attacker with specific business privileges could submit specially crafted input, which is interpreted as executable ABAP code. Successful exploitation could allow the attacker to execute arbitrary ABAP code in the system.
- CVE-2026-87689Critical
Metasploit Framework Web Service REST API (msf-ws) exposes the credential store through Msf::WebServices::CredentialServlet. The update (PUT) and delete (DELETE) handlers for /api/v1/credentials omit the authentication call, unlike other routes. Any client able to reach the web service on its default 0.0.0.0:8080 listener can read, modify, or permanently delete every stored credential without authentication. All published versions through 6.5.4 are affected; fixed in 6.5.5 by adding authentication.
- CVE-2026-96119Critical
IBM i versions 7.3, 7.4, 7.5, and 7.6 could allow a remote authenticated attacker to obtain sensitive information or execute arbitrary code on the system due to improper data sanitization by the HTTP Server Administration web application.

Original NVD description (English source)
A stack buffer overflow flaw was found in the GStreamer H.265 codec parser library (gst-plugins-bad). When parsing a buffering period SEI message, the parser uses an incorrect loop bound derived from cpb_cnt_minus1[i] (the loop index) instead of the sub-layer 0 CPB count cpb_cnt_minus1[0] from the referenced Sequence Parameter Set. A crafted H.265 video file or stream can cause the parser to write beyond the bounds of stack-allocated CPB delay arrays, resulting in a crash or potential stack memory corruption.
