The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a critical security flaw impacting the Sudo command-line utility for Linux and Unix-like operating systems to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation in the wild. The vulnerability in question is CVE-2025-32463 (CVSS score: 9.3), which affects Sudo versions prior to

Rob -- W / cors-anywhere instances configured as an open proxy allow unauthenticated external users to induce the server to make HTTP requests to arbitrary targets (SSRF). Because the proxy forwards requests and headers, an attacker can reach internal-only endpoints and link-local metadata services, retrieve instance role credentials or other sensitive metadata, and interact with internal APIs and services that are not intended to be internet-facing. The vulnerability is exploitable by sending crafted requests to the proxy with the target resource encoded in the URL; many cors-anywhere deployments forward arbitrary methods and headers (including PUT), which can permit exploitation of IMDSv2 workflows as well as access to internal management APIs. Successful exploitation can result in theft of cloud credentials, unauthorized access to internal services, remote code execution or privilege escalation (depending on reachable backends), data exfiltration, and full compromise of cloud resour...

Cloud security company Wiz has revealed that it uncovered in-the-wild exploitation of a security flaw in a Linux utility called Pandoc as part of attacks designed to infiltrate Amazon Web Services (AWS) Instance Metadata Service (IMDS). The vulnerability in question is CVE-2025-51591 (CVSS score: 6.5), which refers to a case of Server-Side Request Forgery (SSRF) that allows attackers to

A critical token validation failure in Microsoft Entra ID (previously Azure Active Directory) could have allowed attackers to impersonate any user, including Global Administrators, across any tenant. The vulnerability, tracked as CVE-2025-55241, has been assigned the maximum CVSS score of 10.0. It has been described by Microsoft as a privilege escalation flaw in Azure Entra. There is no

EXECUTIVE SUMMARY CVSS v4 8.7 ATTENTION: Exploitable remotely/low attack complexity Vendor: Hitachi Energy Equipment: Asset Suite Vulnerabilities: Server-Side Request Forgery (SSRF), Deserialization of Untrusted Data, Cleartext Storage of Sensitive Information, Uncontrolled Resource Consumption, URL Redirection to Untrusted Site ('Open Redirect'), Improper Authentication 2. RISK EVALUATION Successful exploitation of this vulnerability could allow attackers to trigger resource consumption or information disclosure through SSRF in Apache XML Graphics Batik, mount a Denial-Of-Service attack via poisoned data in logback, discover cleartext passwords in H2 Database Engine, fill up the file system in Apache CXF, perform open redirect or SSRF attacks through UriComponentsBuilder, and execute arbitrary code in Apache ActiveMQ. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS Hitachi Energy reports that the following products are affected: Asset Suite: Versions 9.6.4.5 and prior 3.2 VULN...

### Summary jinjava’s current sandbox restrictions prevent direct access to dangerous methods such as `getClass()`, and block instantiation of Class objects. However, these protections can be bypassed. By using mapper.getTypeFactory().constructFromCanonical(), it is possible to instruct the underlying ObjectMapper to deserialize attacker-controlled input into arbitrary classes. This enables the creation of semi-arbitrary class instances without directly invoking restricted methods or class literals. As a result, an attacker can escape the sandbox and instantiate classes such as java.net.URL, opening up the ability to access local files and URLs(e.g., file:///etc/passwd). With further chaining, this primitive can potentially lead to remote code execution (RCE). ### Details jinjava templates expose a built-in variable `____int3rpr3t3r____`, which provides direct access to the jinjavaInterpreter instance. This variable was previously abused (see [Add interpreter to blacklist](https:/...

### Impact There are multiple server-side request forgery (SSRF) vulnerabilities in the DragonFly2 system. The vulnerabilities enable users to force DragonFly2’s components to make requests to internal services, which otherwise are not accessible to the users. One SSRF attack vector is exposed by the Manager’s API. The API allows users to create jobs. When creating a Preheat type of a job, users provide a URL that the Manager connects to (see figures 2.1–2.3). The URL is weakly validated, and so users can trick the Manager into sending HTTP requests to services that are in the Manager’s local network. ```golang func (p *preheat) CreatePreheat(ctx context.Context, schedulers []models.Scheduler, json types.PreheatArgs) (*internaljob.GroupJobState, error) { [skipped] url := json.URL [skipped] // Generate download files var files []internaljob.PreheatRequest switch PreheatType(json.Type) { case PreheatImageType: // Parse image manifest url s...

### Impact A Server-Side Request Forgery (SSRF) vulnerability that affects all users running the HackMD MCP server in HTTP mode. Attackers could exploit this vulnerability by passing arbitrary `hackmdApiUrl` values through HTTP headers (`Hackmd-Api-Url`) or base64-encoded JSON query parameters. This allows malicious users to: - Redirect API calls to internal network services - Potentially access sensitive internal endpoints - Perform network reconnaissance through the server - Bypass network access controls The vulnerability affects the HTTP transport mode specifically - stdio mode is not impacted as it only accepts requests from stdio. ### Patches The vulnerability has been patched in version `1.5.0`. Users should: 1. Update to the latest version of the HackMD MCP server 2. Set the `ALLOWED_HACKMD_API_URLS` environment variable to restrict allowed HackMD API endpoints 3. If not set, the server will default to only allowing the official HackMD API URL (`https://api.hackmd.io/v1`)...
