CORS misconfiguration in CoolerControl coolercontrold versions 2.0.0 through 3.x allows unauthenticated remote attackers to read sensitive data and send control commands to the service by exploiting browser-based cross-origin requests from malicious websites. The vulnerability requires user interaction (UI:R) but grants attackers capability to leak information and manipulate daemon operations with a CVSS score of 6.3 (medium).
Cross-Origin Resource Sharing (CORS) misconfiguration in vanna-ai vanna up to version 2.0.2 allows authenticated remote attackers to establish permissive cross-domain policies with untrusted domains, leading to information disclosure. The vulnerability affects the FastAPI/Flask Server component and has publicly available exploit code; however, the vendor has not responded to early disclosure attempts. With a CVSS score of 5.3 and confirmed public exploit availability, this represents a moderate-risk authentication-gated information exposure issue.
Remote code execution in SiYuan desktop application (versions prior to 3.6.2) allows unauthenticated remote attackers to execute arbitrary code with full operating system privileges through CORS misconfiguration. A malicious website can inject JavaScript into the Electron-based application's Node.js context via the permissive API (Access-Control-Allow-Origin: * with Access-Control-Allow-Private-Network: true), which executes with OS-level access when the user next opens SiYuan's interface. No public exploit identified at time of analysis, though CVSS 9.6 (Critical) reflects network-accessible attack vector with low complexity requiring only user interaction (visiting malicious site while SiYuan runs). EPSS data not provided, but the combination of Electron framework exploitation, RCE impact, and trivial attack complexity suggests elevated real-world risk for desktop users.
Cross-Origin Resource Sharing (CORS) misconfiguration in PowerDNS dnsdist's internal webserver allows remote attackers to extract sensitive configuration information from the dashboard through a social engineering attack targeting authenticated administrators. An attacker can trick an admin into visiting a malicious website, which then leverages the misconfigured CORS policy to read dashboard API responses containing running configuration details. The vulnerability requires the internal webserver to be enabled (disabled by default) and user interaction, resulting in limited confidentiality impact with no integrity or availability risk.
Hardcoded wildcard CORS headers (Access-Control-Allow-Origin: *) in the Model Context Protocol Java SDK transport layer enable cross-origin session hijacking, allowing attackers to extract session IDs from victim browsers and relay authenticated requests back to internal MCP servers. The vulnerability affects the HttpServletSseServerTransportProvider and HttpServletStreamableServerTransportProvider classes in mcp-core; no public exploit code has been identified, though the attack requires user interaction (victim visiting attacker-controlled page). CVSS 6.1 reflects the combination of network-accessible vector, low attack complexity, and cross-origin impact, though practical exploitation depends on MCP server deployment architecture.
Cross-origin data exfiltration in Glances XML-RPC server (glances -s) allows any website to steal complete system monitoring data including hostname, OS details, process lists with command-line arguments, and network configuration through CORS misconfiguration. The server sends Access-Control-Allow-Origin: * on all responses and processes XML-RPC POST requests with Content-Type: text/plain without validation, bypassing browser CORS preflight checks. Default deployments run unauthenticated, making all network-accessible instances immediately exploitable. No public exploit identified at time of analysis, though detailed proof-of-concept code is included in the advisory.
HCL Aftermarket DPC version 1.0.0 contains a Cross-Origin Resource Sharing (CORS) misconfiguration that permits authenticated attackers with low privileges to access sensitive user information and potentially perform unauthorized actions on behalf of legitimate users through browser-based attacks. The vulnerability requires user interaction (such as social engineering to visit a malicious webpage) and operates within a single security context, limiting its scope to confidentiality impact with no integrity or availability consequences. No public exploit code has been identified at the time of analysis, and the low CVSS score of 2.6 reflects the high attack complexity and limited practical exploitability despite the theoretical risk of data exposure.
A CORS misconfiguration vulnerability in mcp-memory-service allows any malicious website to perform cross-origin requests to the HTTP API. Versions prior to 10.25.1 of mcp-memory-service from doobidoo are affected, particularly when the HTTP server is enabled with anonymous access, allowing attackers to read, modify, and delete all stored memories without authentication. No KEV listing or public exploitation indicators are currently reported, though the vulnerability's simplicity and the availability of a GitHub security advisory suggest proof-of-concept development would be straightforward.
Misconfigured CORS headers in this web application permit cross-origin requests from any domain, enabling attackers to craft malicious webpages that perform unauthorized actions or exfiltrate sensitive data from victims' browsers when they visit attacker-controlled sites. Although the application is typically deployed on trusted local networks, the vulnerability can be exploited remotely by leveraging victim browsers as intermediaries without requiring direct network access. An attacker can silently harvest credentials, session tokens, or other sensitive information through transparent cross-site requests made on page load.
AVideo (WWBN_AVideo) contains a critical CORS misconfiguration vulnerability that exposes PHP session IDs to any unauthenticated external website, enabling complete account takeover of any logged-in user including administrators. The vulnerability has a working proof-of-concept exploit and requires only that a victim visit an attacker-controlled webpage while logged into AVideo, making it highly exploitable with an 8.1 CVSS score.
