🛡️ Researchers at Obsidian Security disclosed a three-bug chain in the open-source LiteLLM proxy that lets a default low-privilege account escalate to full proxy admin and achieve remote code execution. The combined issue, rated CVSS 9.9, exposes provider keys, decryption secrets, prompts, and responses. Maintainer BerriAI published fixes in LiteLLM v1.83.14-stable (May 2); users should upgrade and audit admin roles, guardrails, callbacks, and keys.

🚨 Enterprises using the open-source AI orchestration platform Langflow are urged to apply a patch for a high-severity path traversal flaw that enables arbitrary file writes and, in some environments, remote code execution. The vulnerability stems from improper handling of uploaded filenames at the /api/v2/files endpoint and was fixed in version 1.9.0, though exploitation has been observed in the wild. Public proof-of-concept code and exposed instances increase risk for unpatched deployments.

🛡️ An attacker served tampered JavaScript used by PushEngage, OptinMonster, and TrustPulse, executing only when a logged-in WordPress administrator loaded the files. The malicious code created an attacker-controlled admin account, installed a hidden plugin backdoor providing remote code execution, and exfiltrated credentials to a fake tidio[.]cc domain. Sansec disclosed the campaign on June 13; PushEngage confirmed exposures that lasted longer than the brief windows seen for the other plugins. Site owners should treat any site that loaded the affected scripts during the window as compromised and perform server-side scans and credential rotations immediately.

🛡️ Splunk released security updates to remediate a critical unauthenticated file operation and remote code execution vulnerability (CVE-2026-20253, CVSS 9.8) affecting certain Splunk Enterprise versions. The flaw stemmed from an unauthenticated PostgreSQL sidecar service endpoint that allowed creation or truncation of arbitrary files. Splunk fixed the issue in 10.0.7 and 10.2.4; Splunk Cloud is not affected because it does not use Postgres sidecars. Users are urged to apply the updates promptly to mitigate exploitation risk.
