CVE-2026-43616 - Detect-It-Easy < 3.21 Path Traversal Arbitrary File Write
CVE ID :CVE-2026-43616
Published : May 4, 2026, 5:33 p.m. | 22 minutes ago
Description :Detect-It-Easy prior to 3.21 contains a path traversal vulnerability that allows attackers to write arbitrary files to the filesystem by crafting malicious archive entries with relative traversal sequences or absolute paths. Attackers can exploit insufficient path normalization during archive extraction to write files outside the intended extraction directory and achieve persistent code execution by overwriting user startup scripts.

CVE-2026-42140 - Server-Side Request Forgery (SSRF) in PlantUML Macro via 'server' parameter
CVE ID :CVE-2026-42140
Published : May 4, 2026, 5:37 p.m. | 19 minutes ago
Description :PlantUML Macro is a macro for rendering UML diagrams from simple textual schemes. Prior to version 2.4.1, the PlantUML Macro is vulnerable to Server-Side Request Forgery (SSRF). The macro allows users to specify an alternative PlantUML server via the server parameter. However, the application does not validate the supplied URL. An attacker can supply an internal IP address or a malicious external URL. The XWiki server will attempt to connect to this URL to "render" the diagram. This issue has been patched in version 2.4.1.

CVE-2026-42231 - n8n: Prototype Pollution in XML Webhook Body Parser Leads to RCE
CVE ID :CVE-2026-42231
Published : May 4, 2026, 7:16 p.m. | 2 hours, 41 minutes ago
Description :n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, a flaw in the xml2js library used to parse XML request bodies in n8n's webhook handler allowed prototype pollution via a crafted XML payload. An authenticated user with permission to create or modify workflows could exploit this to pollute the JavaScript object prototype and, by chaining the pollution with the Git node's SSH operations, achieve remote code execution on the n8n host. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.

Description :n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, a flaw in the Oracle Database node's select operation allowed user-controlled input passed into the Limit field via expressions to be interpolated directly into the SQL query without sanitization or parameterization. In workflows where external input is passed into the Limit field (e.g., from a webhook), an attacker could inject arbitrary SQL and exfiltrate data from the connected Oracle database. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.

CVE-2026-42235 - n8n: XSS via MCP OAuth client
CVE ID :CVE-2026-42235

Description :n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, an unauthenticated attacker could register a malicious MCP OAuth client with a crafted client_name. If a victim user authorized the OAuth consent dialog and a second user subsequently revoked that access, a toast notification would render the injected script. Clicking the link would execute arbitrary JavaScript in the victim's authenticated n8n browser session, enabling credential and session token theft, workflow manipulation, or privilege escalation.

CVE-2026-42236 - n8n: Unauthenticated Denial of Service via MCP Client Registration
CVE ID :CVE-2026-42236
Published : May 4, 2026, 7:16 p.m. | 2 hours, 41 minutes ago
Description :n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, the MCP OAuth client registration endpoint accepted unauthenticated requests and stored client data without adequate resource controls. An unauthenticated remote attacker could exhaust server memory resources by sending large registration payloads, rendering the n8n instance unavailable. The MCP enable/disable toggle gates MCP access but did not restrict client registrations, meaning the endpoint is reachable regardless of whether MCP access is enabled on the instance.

Description :IKUS Rdiffweb before 2.10.5 has an improper authorization flaw that allows an attacker with any valid or stolen access token to act as other users.

CVE-2026-41926 - WDR201A WiFi Extender OS Command Injection via firewall.cgi
CVE ID :CVE-2026-41926
Published : May 4, 2026, 8:16 p.m. | 1 hour, 41 minutes ago
Description :WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the firewall.cgi binary across five request handlers that apply insufficient input validation. Attackers can inject arbitrary shell commands through vulnerable parameters like websURLFilter, websHostFilter, portForward, singlePortForward, and ipportFilter using subshell syntax or unfiltered parameters, with payloads persisting in NVRAM and re-executing on every subsequent firewall.cgi request.

CVE-2026-41927 - WDR201A WiFi Extender Stack-Based Buffer Overflow via firewall.cgi
CVE ID :CVE-2026-41927
Published : May 4, 2026, 8:16 p.m. | 1 hour, 41 minutes ago
Description :WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains a stack-based buffer overflow vulnerability in the firewall.cgi and makeRequest.cgi binaries that allows unauthenticated attackers to overwrite the saved return address by sending a POST request with a Content-Length header exceeding 512 bytes. Attackers can exploit insufficient length validation in the fgets() call to achieve arbitrary code execution through return-oriented programming or return-to-libc techniques.
