The spomky-labs/otphp library is vulnerable to a denial of service (GHSA-g7m4-839x-ch6v) where an unbounded 'digits' parameter in an otpauth provisioning URI causes a DivisionByZeroError, leading to unhandled fatal errors in applications trying to generate or verify OTPs.

A critical vulnerability, CVE-2026-0755, in npm's gemini-mcp-tool package allows for OS command injection on Windows systems due to improper handling of unquoted cmd.exe metacharacters, and arbitrary local file exfiltration via the @file parser when processing untrusted prompt input, leading to potential remote code execution and sensitive data compromise.

CVE-2026-25865 describes an unquoted search path element vulnerability in Yandex Punto Switcher through version 4.5.0.583, allowing local attackers to execute arbitrary code by placing a malicious `RunDll32.exe` earlier in the system's PATH to hijack the application's insecure `WinExec` call, leading to arbitrary code execution with affected user privileges.

Adversaries with privileged Azure RBAC roles are exploiting the Azure VM Serial Console to gain SYSTEM/root access on virtual machines, bypassing network controls like NSGs and JIT policies, with detections focusing on unusual user and source network combinations.

A remote, unauthenticated attacker can exploit an unpatched Server-Side Request Forgery (SSRF) vulnerability in Crawl4AI Docker API versions up to 0.8.9, specifically targeting the `/crawl/stream` endpoint, to read internal network services and cloud-metadata endpoints, potentially exposing sensitive information like IAM credentials.

An attacker can achieve unauthenticated remote code execution (RCE) in Crawl4AI Docker deployments by injecting malicious Chromium launch arguments, such as `--utility-cmd-prefix` and `--no-zygote`, into the `browser_config.extra_args` field of the API request, allowing for arbitrary command execution as the container's runtime user.

On June 17, 2026, Drupal released critical security advisories (AV26-615) addressing multiple vulnerabilities in Drupal core and several modules including Plotly.js Graphing, Flag attendance field, and Formatter Field, which, if unpatched, could allow remote attackers to compromise affected web servers and sensitive data.

An unauthenticated attacker can exploit CVE-2026-55204, a null pointer dereference vulnerability in HAProxy through version 3.4.0, by triggering excessive HPACK dynamic table insertions under memory pressure, causing HAProxy worker processes to crash and resulting in a denial of service.

An integer overflow vulnerability (CVE-2026-55203) in HAProxy through version 3.4.0 allows malicious FastCGI backends to desynchronize the FCGI framing parser, leading to request routing errors, response smuggling, or memory safety issues.

Adversaries are modifying OAuth application redirect URIs (ReplyUrls) in Microsoft Entra ID to intercept OAuth authorization codes and steal tokens, granting unauthorized access without new application registration or user consent.

A sophisticated threat actor, having compromised an existing guest account in Microsoft Entra ID, can establish persistent access and elevate privileges by performing a Guest-to-Member account conversion, which grants full directory read access and bypasses Conditional Access restrictions, enabling stealthy long-term access and reconnaissance.

An attacker with elevated privileges abuses the Microsoft Entra ID Temporary Access Pass (TAP) feature to bypass multi-factor authentication (MFA), gain unauthorized access to target user accounts, and establish persistence by registering new authentication methods.

Attackers are actively exploiting the OAuth device code flow in Microsoft 365 to bypass multi-factor authentication (MFA) and gain initial access, leveraging phishing kits like Kali365 and tradecraft similar to Storm-2372 to harvest MFA-satisfied tokens from non-compliant or attacker-controlled devices, and subsequently establishing persistence through device registration.

Adversaries may create custom administrative roles in Google Workspace to establish persistence with tailored, elevated permissions, which are then assigned to compromised or attacker-controlled accounts to bypass security controls, grant OAuth access, or modify mail routing.

Adversaries leverage the assignment of administrative roles within Google Workspace to an existing or new user/group, establishing persistence and escalating privileges to gain broad control over the tenant, including bypassing single sign-on.

Adversaries with elevated privileges within Google Workspace may delete custom administrative roles to impede security operations, remove delegated administrator access, or obfuscate their activities during an active incident, leading to disrupted delegated administration, loss of security team access, or hindrance of incident response efforts.

PraisonAI's template loader is vulnerable to a path traversal flaw (GHSA-f44v-7qgw-9gh9) when processing GitHub template URIs, allowing an unauthenticated attacker to write arbitrary files or delete arbitrary directories on the system running PraisonAI, leading to corruption of user configuration, project state, or application data.

Kirby CMS versions prior to 4.9.4 and between 5.0.0-alpha.1 and 5.4.3 are vulnerable to a self-cross-site scripting (self-XSS) flaw, CVE-2026-49276, in the writer field, allowing an attacker to inject malicious JavaScript as the target of a link or email link which, if clicked by an authenticated user before saving, will execute in their browser context, potentially making API requests with their permissions, while Panel plugins using the `<k-writer>` component may be vulnerable to stored XSS if they don't sanitize HTML.

A high-severity cross-site scripting (XSS) vulnerability, tracked as CVE-2026-54002, exists in Kirby CMS versions prior to 4.9.4 and between 5.0.0-alpha.1 and 5.4.3, allowing authenticated Panel users to inject malicious markup into `writer` or `list` fields or via `Sane` API-dependent custom code, leading to stored XSS and potential privilege escalation.

An authenticated user can exploit CVE-2026-54005, a high-severity missing authorization vulnerability in Kirby CMS versions <= 4.9.3 and from 5.0.0-alpha.1 to <= 5.4.3, via the `/api/site/find` REST API route to bypass `pages.access` permissions and retrieve sensitive content and metadata from unauthorized pages.

An unauthenticated remote attacker can leverage a missing authorization vulnerability (CWE-862) in the Pipecat development runner's `/ws` WebSocket endpoint to supply a crafted `callSid` in a handshake message, compelling the server to use its configured Twilio, Telnyx, or Plivo credentials to issue authenticated API requests that terminate active calls, resulting in denial of service and credential abuse.

A critical stored Cross-Site Scripting (XSS) vulnerability, CVE-2026-44727, exists in `jupyter_server` versions up to 2.19.0 due to a missing `sandbox` directive in Content-Security-Policy (CSP) headers, allowing authenticated attackers to craft malicious notebooks that exfiltrate victim tokens and achieve kernel Remote Code Execution (RCE) when viewed.

A critical external initialization vulnerability (CVE-2026-54003) in Kirby CMS allows unauthenticated attackers to create an initial admin account on sites running behind a reverse proxy, specifically when the proxy utilizes `Forwarded: for=...`, `X-Client-IP`, or `X-Real-IP` headers, bypassing Kirby's `isLocal` check and enabling remote Panel installation with full administrative access.

A remote, unauthenticated attacker may exploit a deserialization of untrusted data vulnerability (CVE-2026-8024) in ibaPDA (versions prior to 8.14.0) or ibaDatCoordinator (versions prior to 4.0.7) to gain full access to the affected systems, potentially leading to arbitrary code execution and system compromise.

A high-severity vulnerability in dadrus/heimdall (versions <= 0.17.16) enables attackers to spoof client IP addresses by injecting unvalidated or malformed values into `Forwarded` or `X-Forwarded-For` HTTP headers, potentially bypassing access controls or propagating malicious IP data to upstream services when `trusted_proxies` is configured.

Attackers can exploit Heimdall proxy versions <= 0.17.16 operating in proxy mode by injecting malicious values into the `Host` HTTP header, leading to the construction of a manipulated `Forwarded` header that can spoof client IP addresses for upstream services, potentially bypassing IP-based access controls.

A command injection vulnerability (CVE-NONE) exists in PraisonAI's `praisonaiagents` package (versions <= 1.6.48) where unsanitized LLM-controlled parameters are directly interpolated into IMAP SEARCH commands, allowing attackers to craft malicious prompts to inject arbitrary IMAP commands, leading to unauthorized email exfiltration, deletion, or denial-of-service when email tools are configured.

The npm package `praisonai` versions 1.2.3 through 1.7.1 contain a network isolation bypass vulnerability (GHSA-gqmf-56h7-rrpf) in its `SandboxExecutor` component's `network-isolated` mode, allowing non-proxy-aware client commands to establish direct network connections, leading to potential data exfiltration and access to internal services.

A critical command injection vulnerability exists in the `npm:praisonai` package versions >= 1.2.3 and <= 1.7.1, where the `SandboxExecutor`'s `allowedCommands` policy is bypassed by allowing arbitrary shell command chaining after an allowlisted command, leading to remote code execution with the PraisonAI process privileges.

The npm package `praisonai` versions 1.5.1 through 1.7.1 contains a command injection vulnerability (GHSA-5jv7-2mjm-h6qj) in its `utility-tools.shell()` helper, which allows attackers to bypass a 'safe read-only' command allowlist by appending arbitrary shell commands with metacharacters after an allowed command, leading to arbitrary code execution with the PraisonAI process privileges.
