Threat briefs

SQLFluff versions prior to 4.2.0 are vulnerable to uncontrolled resource consumption (CVE-2026-46374), allowing an attacker to cause a denial of service by submitting a maliciously crafted, long SQL query.

The dasel selector lexer is vulnerable to an index-out-of-range panic when tokenizing a quoted string that ends with a trailing backslash (e.g., `"\` or `'\`), leading to a process crash if an attacker can control the selector string.

Dasel versions 3.0.0 to 3.3.1 are vulnerable to a denial-of-service attack (CVE-2026-46378) where the selector lexer enters a non-terminating loop when tokenizing an unterminated regex pattern, causing 100% CPU usage on one core, which can be triggered by an attacker-controlled selector/query string.

SillyTavern version 1.17.0 is vulnerable to server-side request forgery (SSRF) via the `/api/search/searxng` route, allowing authenticated low-privilege users to control the `baseUrl` parameter for outbound server-side fetches, potentially disclosing sensitive information from internal HTTP services or cloud metadata endpoints.

A maliciously crafted SQL query with excessive nesting can cause a denial of service by exhausting resources when parsed by SQLFluff versions prior to 4.1.0; version 4.1.0 introduces a configurable recursion limit to mitigate this vulnerability.

An unauthenticated remote peer can exhaust the disk storage of any `@libp2p/kad-dht` node running in server mode by sending an unbounded stream of `PUT_VALUE` messages with crafted keys to bypass validation and cause disk exhaustion.

Coder is vulnerable to a PKCS#7 signature bypass in Azure instance identity (CVE-2026-46354), allowing unauthenticated agent token theft via a forged vmId, enabling access to Git SSH private keys, OAuth access tokens, and workspace secrets.

The Penpot MCP module's ReplServer binds to all interfaces and exposes an unauthenticated /execute endpoint, allowing remote attackers to execute arbitrary code by sending a POST request with JavaScript code, leading to potential information disclosure and command execution.

Dell published security advisories between May 11 and 17, 2026, addressing vulnerabilities in Dell Enterprise Sonic Distribution, Dell Live Optics Collector, Intel 800 Series Ethernet Adapters, Dell PowerEdge with AMD Graphics, and PowerScale InsightIQ, prompting users to apply necessary updates.

The SHub Reaper stealer combines credential theft, wallet hijacking, and document exfiltration with persistent backdoor access on macOS, distributed through fake WeChat and Miro installers while spoofing Apple, Google, and Microsoft to evade detection.

The MCP router exposes an initialize method code path that bypasses the gateway JWT session validator and rewrites the upstream :authority header, gated only by a shared header value, allowing attackers to bypass authorization and access backend services.

Bandit versions 1.6.0 through 1.11.0 are vulnerable to an unauthenticated denial-of-service (CVE-2026-39806) via a chunked request with trailers, where sending a request with `Transfer-Encoding: chunked` and a trailer field causes the connection's worker process to spin forever in an infinite recursion, exhausting the listener pool and rendering the server unresponsive.

Bandit's HTTP/1 chunked-body reader silently drops the request size cap, leading to excessive memory buffering. An unauthenticated attacker can crash Bandit-fronted Phoenix/Plug applications by sending a single 'Transfer-Encoding: chunked' request to any URL, causing BEAM memory exhaustion and a denial-of-service.

Mozilla released security updates on May 19, 2026, addressing vulnerabilities in Firefox versions prior to 151, Firefox ESR versions prior to 115.36, and Firefox ESR versions prior to 140.11.

9router versions 0.4.30 to 0.4.33 are vulnerable to unauthenticated remote code execution, allowing network-adjacent attackers to execute arbitrary OS commands by registering and triggering malicious plugins through unprotected API endpoints.

Kopia's HTTP server, when started without `--without-password`, accepts unauthenticated requests which can lead to arbitrary command execution as the Kopia process user via `-oProxyCommand` in `sshArguments` for SFTP backends with `externalSSH: true`. An attacker-supplied storage configuration is forwarded to `blob.NewStorage`, and the `sshArguments` are split on spaces and passed directly to `exec.CommandContext("ssh")`, resulting in command injection.

The Kirki plugin for WordPress is vulnerable to arbitrary file deletion via CVE-2026-8073 due to insufficient file path validation and a missing capability check in the 'downloadZIP' function, allowing unauthenticated attackers to delete files within the WordPress uploads directory.

TeamPCP compromised the PyPi package durabletask (versions 1.4.1, 1.4.2, and 1.4.3), stealing credentials for AWS, Azure, GCP, K8s, and Vault, brute-forcing passwords from password managers, and exfiltrating shell history before propagating to up to 5 targets via AWS SSM and Kubernetes.

Windmill versions prior to 1.703.2 are vulnerable to incorrect default permissions in the nsjail sandbox configuration, allowing authenticated users to inject malicious entries into critical system files, leading to potential privilege escalation and man-in-the-middle attacks.

The Shai-Hulud campaign is back and targets maintainer accounts to publish malicious code directly into the software supply chain via npm, recently hitting the Ant Design (AntV) ecosystem and potentially exposing downstream developers to credential theft and remote code execution.

Budibase is vulnerable to persistent stored XSS (CVE-2026-46426) due to unrestricted file upload of active content by authenticated users, leading to potential session cookie theft and account takeover.

HPE published a security advisory (AV26-477) addressing a critical vulnerability in HPE Unified OSS Console (UOC) version 3.1.20 and prior, potentially leading to unauthorized access and control of network operations.

An application that passes an overlong ciphertext buffer to `libcrux_chacha20poly1305::encrypt` or `libcrux_chacha20poly1305::xchacha20_poly1305::encrypt` can experience a panic, leading to a crash if the buffer length is attacker-controlled, affecting libcrux-chacha20poly1305 versions prior to 0.0.8.

The AVX2 implementation of ML-DSA verification in libcrux-ml-dsa mishandles an edge case in the `use_hint` function, potentially allowing an attacker to craft an invalid signature that is accepted by the verifier if the AVX2 implementation is used.

The Motorola Factory Test component (com.motorola.motocit) contains an improper authentication vulnerability, allowing a local attacker to bypass permission checks and access protected device settings by leveraging a writable file descriptor in external storage to open a TCP server.

Composer leaks GitHub OAuth tokens in GitHub Actions logs if they do not match the expected format due to a validation regex, leading to potential unauthorized access.

ZKTeco CCTV cameras are vulnerable to authentication bypass due to an undocumented configuration export port that does not require authentication and exposes critical information about the camera, such as open services and account credentials, as tracked by CVE-2026-8598.

Multiple vulnerabilities exist in ScadaBR version 1.2.0, including CVE-2026-8602, CVE-2026-8603, CVE-2026-8604, and CVE-2026-8605, which could allow for unauthenticated remote code execution.

A path traversal vulnerability (CVE-2025-3465) in ABB CoreSense HM and CoreSense M10 allows unauthenticated local users to access restricted directories, potentially leading to system compromise and information exposure; patch to CoreSense™ HM v2.3.4 and CoreSense™ M10 v1.4.1.31.

A cross-site scripting vulnerability, CVE-2026-4293, exists in multiple Kieback & Peter DDC Building Controllers that could allow an attacker to take control of the victim's browser.
