From SQLi to RCE – Exploiting LangGraph’s Checkpointer
Check Point Research reports three flaws in LangGraph’s persistence layer (checkpointers), impacting the SQLite checkpointer (CVE-2025-67644 and CVE-2026-28277) and the Redis checkpointer (CVE-2026-27022). In the SQLite path, a filter-related SQL injection can be chained with unsafe msgpack deserialization to reach remote code execution, since attacker-supplied checkpoint data is deserialized during state history retrieval. This matters most for teams self-hosting LangGraph and exposing getstatehistory() with a user-controlled filter; LangChain’s managed LangSmith Deployment using PostgreSQL is not affected. Fixes are available in langgraph-checkpoint-sqlite 3.0.1+, langgraph 1.0.10+, and langgraph-checkpoint-redis 1.0.2+.

ITScape KVM Escape: Public PoC Exploit Threatens Cloud Hosts
A proof-of-concept for an ITScape KVM escape issue has been publicly released, tracked as CVE-2026-46316. The flaw impacts KVM/arm64 environments by enabling untrusted guest virtual machines to break isolation and execute commands on the host with kernel (root) privileges. Because the bug resides in-kernel KVM and can be triggered from guest-side actions, it significantly raises risk for multi-tenant public cloud providers and tenants running affected kernel versions.
Critical Jenkins Security Advisory 2026: Patch Multiple Flaws
A new Jenkins security advisory released in 2026 reports several high-impact issues affecting Jenkins, including remote code execution and data exposure via deserialization (CVE-2026-53435) and additional open redirect and XSS-related weaknesses (CVE-2026-53436, CVE-2026-53437, CVE-2026-53441). The advisory also addresses missing authorization checks and information leakage that can let attackers disrupt job queues, view sensitive user data, and extract plaintext secrets from POST config.xml submissions (CVE-2026-53438, CVE-2026-53439, CVE-2026-53442). Because these flaws can be exploited against CI/CD deployments, Jenkins administrators should apply the published patches immediately—upgrading to version 2.568 for weekly releases or 2.555.3 for LTS.
Important GitLab Security Updates Address 12 Vulnerabilities
GitLab released security updates for self-managed Community and Enterprise Editions, including versions 19.0.2, 18.11.5, and 18.10.8, addressing 12 vulnerabilities. The fixes include high-impact issues such as CVE-2026-6552 (improper access control in Group SAML Identity API), CVE-2026-10087 (XSS in the Analytics Dashboard), CVE-2026-7250 (unauthenticated DoS), and multiple injection/authorization problems like CVE-2026-8589 and CVE-2026-10733. Administrators should upgrade promptly because these bugs can enable account takeover, execute client-side code, disrupt availability, and expose or alter sensitive data.
Critical NVIDIA DALI Vulnerabilities Require Immediate Action
NVIDIA has released a June 2026 security update for NVIDIA DALI addressing two critical issues affecting versions 0.0 through 2.0. The flaws are tracked as CVE-2026-24180 (heap-based buffer overflow) and CVE-2026-24181 (improper index validation), and successful exploitation could enable code execution, data tampering, denial of service, or information disclosure across any supported platform/OS. Organizations using NVIDIA DALI should update to DALI v2.1 or later immediately to reduce exposure.
PhpSpreadsheet RCE Vulnerability: PoC Exploit Disclosed for 312 Million Users
A critical remote code execution issue tracked as CVE-2026-45034 has been disclosed in PhpSpreadsheet (PHPOffice), along with public proof-of-concept exploit details. The problem stems from a patch-bypass weakness in File::prohibitWrappers that attackers can evade by manipulating wrapper input, allowing dangerous file handling and, depending on the PHP version and application behavior, potential deserialization to reach RCE. Versions in the 1.x series up to 1.30.4 are reported as vulnerable, and upgrading to 1.30.5 is recommended to reduce exposure.
