Hive Metastore SQLi scores 9.8, PraisonAI auth fails wide open

A SQL injection in Apache Hive partition names (CVE-2026-49845, CVSS 9.8) plus an "auth fails open" bypass in PraisonAI (CVE-2026-55533, CVSS 8.2). Also: Coroot OAuth hijack, LACT Polkit race condition, and NVIDIA NemoClaw command injection.

No fires today, but one worth your attention. CVE-2026-49845 is a SQL injection in Apache Hive Metastore that scores a 9.8. The real blast radius is narrower than that number suggests (scoped to partition metadata, requires direct SQL mode), but if you run Hive with default settings, don't sleep on it. Four more bugs round out the list, including an auth-bypass in PraisonAI that fails wide open when no API key is configured.

CVE-2026-55533

NVD
8.2
CVSS
Patch within 24h HIGH
PraisonAILinux

PraisonAI's authentication middleware silently allows all requests when the expected API key or JWT secret isn't configured. If your Recipe server is exposed to the network, anyone can POST to /v1/recipes/run without credentials, even though you think auth is turned on. This is a classic "auth fails open" bug.

Affected estate
Anyone running PraisonAI before version 4.6.58 with a network-exposed Recipe server
How to check
Check your installed version with 'pip show praisonai'. Verify whether PRAISONAI_API_KEY and PRAISONAI_JWT_SECRET are set in the server's environment.
Included because
unauthenticated; internet-facing; authentication bypass; CVSS 8.2
Action
Upgrade to PraisonAI 4.6.58 via pip. Restrict network access to the Recipe server endpoint if you can't upgrade immediately.
Why it matters
An unauthenticated attacker can execute arbitrary recipe runs on your server, bypassing what you believe is working authentication.

CVE-2026-79786

NVD
7.1
CVSS
Patch this week HIGH
CorootLinux

Coroot's MCP OAuth endpoint lets anyone register a new OAuth client with any redirect URI, no authentication required. An attacker registers a client pointing to their own server, sends a crafted authorization link to a signed-in user, and captures the authorization code when the user clicks "approve." That code can be exchanged for an access token, giving the attacker full control of the victim's MCP session.

Affected estate
Anyone running Coroot with the MCP OAuth dynamic client registration endpoint exposed
How to check
Try sending an unauthenticated POST to the dynamic client registration endpoint with an arbitrary redirect_uri. If it succeeds, you're vulnerable.
Included because
unauthenticated; internet-facing; session hijack via OAuth redirect; CVSS 7.1
Action
Update Coroot to the fixed version. If you can't update yet, block external access to the dynamic client registration endpoint.
Why it matters
Attackers can hijack MCP sessions of any signed-in user through a phishing link, gaining their access level.

CVE-2026-75037

NVD
7.0
CVSS
Patch this week HIGH
LACTLinux

LACT (a Linux GPU control tool) uses Polkit authentication based on the caller's PID to verify privileged requests. A local attacker can exploit a race condition in PID recycling to bypass authentication and run privileged LACT operations without proper authorization. This requires local access to the machine.

Affected estate
Linux users running LACT version 0.10.0 or earlier for GPU management
How to check
Run 'lact --version' or check your package manager for the installed LACT version.
Included because
local privilege escalation; authentication bypass; CVSS 7.0
Action
Update LACT to the fixed version containing commit d0478fe.
Why it matters
A local attacker can bypass Polkit authentication and perform privileged GPU configuration changes without authorization.

CVE-2026-65099

NVD
7.8
CVSS
Patch this week HIGH
NVIDIA NemoClawLinux

NVIDIA NemoClaw's CLI on Linux is vulnerable to OS command injection. A local attacker who can supply crafted input to the CLI can execute arbitrary commands with the privileges of the NemoClaw process. This could lead to code execution, data tampering, or full system compromise depending on how NemoClaw is deployed.

Affected estate
Linux users running NVIDIA NemoClaw
How to check
Check your installed NemoClaw version against NVIDIA's security bulletin for the fixed version number.
Included because
command injection; code execution; CVSS 7.8; common vendor
Action
Update NemoClaw to the patched release listed in the NVIDIA security advisory.
Why it matters
Command injection in the CLI can give an attacker code execution at the privilege level of the NemoClaw process.
