CVE Vulnerability Catalog

Token Optimizer MCP measures token savings per AI coding agent, optimizes context, and shares a live local knowledge graph across 16 CLI clients. Prior to version 5.1.0, the dashboard HTTP server in token-optimizer-mcp exposes /api/session-summary and /api/session-events with no authentication middleware — any network-accessible client can reach them without credentials. Both handlers concatenate the caller-supplied sessionId query parameter directly into a filesystem path via path.join, and Node.js normalizes .. segments at resolution time, allowing an unauthenticated attacker to read any .jsonl file reachable from the server's filesystem. This issue has been patched in version 5.1.0.

FreePBX is an open source IP PBX. Prior to versions 16.0.40 and 17.0.7, a critical remote code execution (RCE) vulnerability exists in the superfecta module due to unsafe inclusion of arbitrary PHP files, allowing authenticated attackers to execute arbitrary PHP code on the server with the privileges of the web server user. Authentication with a known username is required. The vulnerability is rooted in the options and save_options cases in the Superfecta module's AJAX handler. The code dynamically includes PHP files from the sources/ directory based on user-supplied input. This allows an attacker to execute arbitrary code when combined with arbitrary directory creation (e.g., via the backup module) and file uploads that reveal full paths (e.g., via the soundlang module). This issue has been patched in versions 16.0.40 and 17.0.7.

FreePBX is an open source IP PBX. Prior to versions 16.0.72 and 17.0.7, a critical vulnerability exists in the FreePBX backup Module that allows authenticated attackers to execute arbitrary code on the server. Authentication with a known username that has sufficient access permissions and/or write access to backup files is required. This vulnerability is caused by improper path sanitization in the backup restore functionality, enabling attackers to upload malicious PHP files to the web root directory. This issue has been patched in versions 16.0.72 and 17.0.7.

FreePBX before versions 16.0.10 and 17.0.5 contains a critical vulnerability in the sound language upload and conversion functionality that allows an authenticated attacker to perform arbitrary file writes, leading to remote code execution (RCE). Authentication with a known username is required. The issue stems from insufficient path sanitization in the file conversion process, enabling path traversal attacks that place malicious PHP files in the web server's root directory.

FreePBX before versions 16.0.39 and 17.0.7 allows users authenticated via User Control Panel (UCP) to execute arbitrary commands on the PBX as the webserver user (typically asterisk) using specially crafted HTTP strings. Authenticated access to UCP is required. The issue is due to insufficient sanitization of certain URL parameters used by UCP, allowing binaries to be executed on the host server by carefully chaining commands.

Bluehood monitors local bluetooth activity. Prior to version 0.7.1, when auth_enabled is set in Bluehood, only the HTML page handlers enforced session validation. The /api/* handlers (settings, devices, groups, per-device endpoints including /api/device/{mac}/notes) called no auth check at all. A network attacker reachable on the dashboard port could read Bluetooth tracking data and modify application state — including the heartbeat URL, prune retention, device groups, and per-device notes — without a session cookie. This issue has been patched in version 0.7.1.

FreePBX before versions 16.0.4 and 17.0.6 contains a critical flaw in the Music on Hold (MoH) module that allows authenticated attackers to execute arbitrary system commands with the privileges of the Asterisk service. Authentication with an existing FreePBX administrator account is required. The root cause is that the module accepts a POST parameter defining a custom Asterisk application, stored without sanitization, and later written directly to the musiconhold_additional.conf configuration file, allowing injection of arbitrary commands.

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.5.1, the Address6 isLinkLocal method in src/ipv6.ts recognizes only fe80::/64 instead of the complete fe80::/10 IPv6 link-local range. An attacker-controlled address elsewhere in fe80::/10 can therefore pass a trust-boundary check that relies on isLinkLocal. The same address is identified as link-local by getType and getScope, exposing the inconsistent classification. A successful bypass can reach an on-link host outside the intended trust boundary. This issue is fixed in version 10.5.1.

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.7.1, the isInSubnet and isHostInSubnet methods in src/common.ts compare masked binary strings without validating that both operands use the same IP family. A cross-family containment check whose leading address bits match makes the masked strings compare equal even though IPv4 and IPv6 do not share an address space. An allowlist or denylist decision can therefore classify an address outside the intended range as contained. This issue is fixed in version 10.7.1.

The ip-address library before version 10.7.1 accepts unbounded strings in the Address6 constructor, Address6.isValid, and parse code in src/ipv6.ts, expanding invalid characters through RE_BAD_CHARACTERS into large diagnostics. Material impact occurs only when an application accepts a very large attacker-controlled field and passes it to Address6 parsing without an earlier length bound. Common URL and header limits, and common body-parser defaults, generally constrain the effect; megabyte-scale fields can cause a synchronous stall and high transient memory use, approximately 16 MiB can trigger an invalid string length exception, and process termination occurs at approximately 32 MiB.

In the ip-address library from version 10.2.0 to 10.5.1, the Address6 isPrivate classifier in src/ipv6.ts does not recognize the NAT64 local-use range 64:ff9b:1::/48. Applications that combine isPrivate, isLoopback, and isLinkLocal for a trust-boundary decision can treat an internal IPv4 destination encoded through that range as external. Exploitation depends on a server network using an operator-selected NAT64 prefix within the local-use range.

Axios from 0.28.0 until 0.34.0 and 1.15.1 until 1.20.0 processes inherited serialization options and visitor properties supplied through prototype pollution. A separate same-process prototype-pollution flaw supplies inherited dots, indexes, metaTokens, maxDepth, visitor, or Blob values before object serialization. The inherited options alter toFormData field naming and data interpretation, maxDepth can force request failure, Blob changes value handling, and a polluted visitor can execute when an attacker already has the stronger ability to inject a function.

In Axios from version 1.7.0 to 1.20.0, the fetch adapter constructs a Request with sanitized resolvedOptions but then calls fetch with the original fetchOptions. A separate same-process prototype-pollution flaw populates Object.prototype.headers so fetchOptions.headers resolves through inheritance. The inherited fetchOptions.headers value overrides the sanitized Request headers through the second argument to fetch after Request construction. Attacker-controlled request headers can alter authorization, caching, metadata-service access, or application-specific behavior.

Axios from 1.17.0 until 1.20.0 in the fetch adapter bypasses the maxRedirects: 0 redirect policy. An Axios request uses the fetch adapter with maxRedirects set to zero and receives a redirect response, but the underlying fetch implementation follows the redirect instead of returning the redirect response unchanged. The redirected request can access internal responses or reach state-changing internal endpoints despite redirects being disabled.

Axios from 1.15.0 until 1.20.0 in shouldBypassProxy applies a quadratic trailing-dot regular expression to redirect hostnames. When HTTP_PROXY or HTTPS_PROXY is configured, NO_PROXY or no_proxy is non-empty, redirects are followed, and a crafted redirect Location contains many dots followed by a non-dot character, the regular expression can backtrack quadratically, blocking the Node.js event loop and causing denial of service.

Axios from 1.15.2 until 1.20.0 in the Node HTTP adapter in lib/adapters/http.js supplies request options without an own createConnection value. A separate same-process prototype-pollution flaw places a function on Object.prototype.createConnection. Node resolves and invokes the inherited createConnection socket factory, allowing the attacker-controlled function to select the transport endpoint. The attacker endpoint can receive request headers and bodies, including credentials, and return attacker-controlled responses while the URL appears legitimate.

In Axios from version 1.0.0 to 1.20.0, the dispatchRequest function normalizes inherited Object.prototype.headers from a replacement request configuration. A separate same-process prototype-pollution flaw sets Object.prototype.headers, and trusted request interceptors return a new ordinary configuration without an own headers property. After the interceptor chain, dispatchRequest resolves the inherited headers during normalization. Downstream request processing can observe attacker-controlled headers, including authorization-related values.

Axios from 1.16.1 until 1.20.0 in the RFC 2397 regular expression allows slash characters on both sides of the media-type separator. An application passes an attacker-controlled malformed data URL containing many slash characters and no comma. The JavaScript regular-expression engine explores many separator placements before rejecting the URL. Excessive backtracking can block the Node.js event loop and cause denial of service.

In Axios from version 0.27.2 to 0.34.0 and 1.20.0, default-instance requests that omit an explicit method can read an inherited method value from Object.prototype. If another vulnerability in the same process pollutes Object.prototype.method, calls such as axios.request({ url }) and axios({ url }) can send a state-changing HTTP method instead of the expected default GET. Axios does not create the prototype pollution source. This is a read-side gadget in axios request dispatch.

Axios from 1.13.0 until 1.20.0 in Http2Sessions does not install adequate error handling for a ClientHttp2Session during Axios HTTP/2 session initialization or reuse. A request uses httpVersion: 2 and the ClientHttp2Session emits an error during session initialization or reuse. The unhandled session error escapes normal Promise rejection handling. The uncaught error can terminate the Node.js process and cause denial of service.
