Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

CVE-2026-117603
Medium

Electrum before 4.7.2 contains a spending limit bypass vulnerability in the Nostr Wallet Connect plugin that allows malicious NWC clients to exceed daily_limit_sat by exploiting non-atomic budget checks and millisatoshi truncation.

CVE-2026-117602
High

CVE-2026-117573
HighEPSS 53%

hagent through commit 761eec6 contains an OS command injection vulnerability. MCP clients can execute shell commands by injecting metacharacters into the args parameter of the hagent_arduino and hagent_esp32 tools, which are interpolated into arduino-cli and idf.py commands run via subprocess.run(shell=True).

CVE-2026-117570
Medium

nmap-mcp through commit 3636afa contains an improper allowlist validation vulnerability in the scan_vulnerabilities tool that lets callers run blocked NSE script categories. MCP clients or prompt-injected agents can pass categories like exploit, dos, brute, or intrusive to nmap --script.

CVE-2026-117569
HighEPSS 52%

Kali-GPT through commit a608c74 contains an OS command injection vulnerability in execute_tool() in kali_gpt/tools/mcp_server.py. MCP clients can run commands via unsanitized scanner parameters such as target, ports, domain, wordlist, or url, executed via subprocess.run with shell=True.

CVE-2026-117568
High

mcp-ffmpeg through 1.0.5 contains an OS command injection vulnerability. Attackers can run shell commands by supplying crafted videoPath or outputDir values to the resize-video, extract-audio and get-video-info tools, embedding $(), backticks or a closing double quote in an existing file or directory name.

CVE-2026-117567
HighEPSS 51%

esp-mcp through commit 28afddf contains an OS command injection vulnerability. Attackers can run arbitrary commands by supplying shell metacharacters in MCP tool parameters such as target, port, project_path, or project_name passed to asyncio.create_subprocess_shell.
