A command injection vulnerability (CVE-2026-44190, CWE-78) in the Ansible Lightspeed Visual Studio Code extension allows remote attackers to execute arbitrary commands on a user's system due to improper validation of the `ansible.python.activationScript` setting, leading to complete system control when a malicious project is opened.

Multiple vulnerabilities in Aruba AOS-CX can be exploited by an attacker to bypass security measures, execute arbitrary code, and manipulate files, which could lead to compromise of the network device.

A local attacker can exploit multiple vulnerabilities found in Ubuntu Linux and the snapd component of Canonical Snap, leading to unauthorized information disclosure, privilege escalation to gain root access, and the ability to bypass existing security measures on the affected system.

A remote, highly privileged attacker can exploit multiple vulnerabilities in SolarWinds Serv-U to execute arbitrary code as Root, gain administrator privileges, take over accounts, disclose confidential information, or perform Cross-Site Scripting attacks.

A vulnerability in Veeam Backup & Replication allows a local attacker to escalate privileges on the affected system.

A local attacker can exploit a vulnerability within Ansible software to execute arbitrary code on the affected system, potentially leading to further compromise or unauthorized actions on the host where Ansible is running.

Multiple vulnerabilities exist in Red Hat Ansible Automation Platform, stemming from issues in components such as node-tar, linkify-it, protobufjs, brace-expansion, fast-uri, and DOMPurify. A remote, unauthenticated attacker can exploit these flaws to bypass security measures, perform Cross-Site Scripting (XSS) attacks, manipulate data, trigger Denial-of-Service (DoS) conditions, or execute arbitrary code on the affected system.

A vulnerability in the avahi service allows a local attacker to perform a Denial of Service (DoS) attack, potentially leading to the unavailability of services or the system itself.

A remote, unauthenticated attacker can exploit a vulnerability in libarchive to initiate a Denial of Service attack, disrupting the availability of services or systems utilizing the affected library.

Information has been published regarding CVE-2026-64191, which addresses an issue in the i2c stub related to rejecting I2C block transfers with invalid lengths.

The WP Foodbakery plugin for WordPress, specifically versions up to and including 4.9, is vulnerable to arbitrary file deletion (CVE-2026-15802) due to insufficient file path validation, allowing authenticated attackers with subscriber-level access to delete critical server files, potentially leading to remote code execution.

A denial-of-service vulnerability (CVE-2026-59200) exists in Pillow's `PdfParser.PdfStream.decode()` function across versions 5.1.0 to 12.2.x, allowing an unauthenticated attacker to craft a malicious PDF file that, when processed by a vulnerable application, triggers excessive memory allocation (e.g., a ~950 KB file expanding to 1 GB), leading to server Out-of-Memory termination or severe service degradation.

An easily exploitable vulnerability, CVE-2026-47063, in Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition allows unauthenticated attackers with network access to achieve unauthorized creation, deletion, or modification of critical data via API exploitation, impacting data integrity.

A remote SQL injection vulnerability (CVE-2026-16484) exists in SourceCodester Class and Exam Timetabling System 1.0, specifically within the /edit_subjecta.php file, allowing an unauthenticated attacker to manipulate the 'ID' argument to inject malicious SQL commands, potentially leading to data compromise or unauthorized access, with public exploits available.

The `fast-uri` library, in versions prior to 4.1.1, 3.1.4, and 2.4.3, is vulnerable to a host confusion issue (CVE-2026-16221) due to its failure to treat a literal backslash as an authority delimiter, enabling attackers to bypass host-based security policies via Server-Side Request Forgery (SSRF) or unauthorized access to internal resources.

A vulnerability in fast-xml-parser allows an attacker to bypass entity expansion limits by crafting XML documents with multiple DOCTYPE declarations, leading to excessive CPU usage, memory exhaustion, and denial of service.

Multiple high-severity vulnerabilities, including CVE-2026-33327, CVE-2026-33328, CVE-2026-35590, and CVE-2026-35591, have been identified and patched in the libvips dependency used by the sharp image processing library, affecting users processing untrusted input with sharp versions prior to 0.35.0 or globally installed libvips prior to 8.18.3.

An incomplete fix for GHSA-72hv-8253-57qq in `jackson-core` versions 2.18.6, 2.21.1, and potentially 3.0.x/3.1.x, allows attackers to bypass `maxNumberLength` constraints in the non-blocking JSON parser by streaming JSON numbers in small chunks, leading to unbounded memory accumulation and denial of service in reactive applications.

A critical vulnerability in Gitea allows an authenticated, low-privileged user to exfiltrate internal Git repositories by exploiting a validation bypass, where Gitea's initial URL validation for repository migration is circumvented by the Git command-line client's default behavior of following HTTP redirects to otherwise blocked internal IP addresses, leading to server-side request forgery (SSRF) and the theft of sensitive code, credentials, and configuration into an attacker-controlled repository, with persistent exfiltration possible through pull mirrors.

An improper authorization vulnerability in Gitea's OAuth2 sign-in callback mechanism (CVE-2026-58422) allows users with linked external identity providers to unilaterally re-enable their administrator-disabled accounts, regaining full access and bypassing security controls.

An incomplete Server-Side Request Forgery (SSRF) protection in Gitea versions prior to 1.26.3 allows authenticated users to bypass the allow-list in webhook delivery and repository migrations, enabling internal network probing and data exfiltration from sensitive services like cloud metadata endpoints.

A server-side request forgery (SSRF) vulnerability in mcp-webresearch version 0.1.7 allows attackers to bypass URL protocol validation by supplying private IP addresses, enabling them to leverage prompt injection to steer an LLM-controlled URL, forcing the server's Playwright browser to access internal network services and cloud instance metadata, which leads to the exfiltration of sensitive internal content, including credentials, into the model's context.

An unauthenticated server-side request forgery (SSRF) vulnerability in Keep (commit 91c75e0) allows attackers to exploit an unprotected healthcheck endpoint by supplying crafted JSON payloads with malicious host values, forcing the backend to issue arbitrary HTTP requests to internal services or cloud metadata endpoints for internal network reconnaissance and theft of cloud credentials.
