CVE-2026-75760 Aug 31, 01:09 HIGH PATCH This Week

Credential leakage in ash_ai (versions 0.1.0 through before 1.0.0) exposes embedding provider API keys and request internals to authenticated API callers via unsanitized error messages. In AshAi.Changes.Vectorize, a failed embedding provider call caused the raw Elixir error struct - which HTTP clients commonly populate with the outbound Authorization header, request URL, and provider response body - to be passed through inspect/1 directly into a user-facing changeset error. AshJsonApi and AshGraphql serialize these changeset errors into API responses, making the full credential material readable by any caller who can trigger a provider failure. No public exploit has been identified at time of analysis, but the trigger condition (oversized or malformed vectorized content) is trivially reachable by any authenticated user of an exposed endpoint.

CVE-2026-47893 Aug 27, 06:17 HIGH This Week

Spring WebFlux applications that enable WebSocket connections leak request headers - potentially containing Authorization tokens, session cookies, or API keys - through exception reason messages exposed over the WebSocket channel. All maintained Spring Framework release trains from 5.2.x through 7.0.x are affected, covering the vast majority of actively deployed Spring reactive applications. The vulnerability is classified as information disclosure (CWE-209), and while the CVSS score is 7.5, the EPSS score of 0.14% (4th percentile) indicates very low observed exploitation probability; no public exploit or CISA KEV listing exists at time of analysis.

CVE-2026-77076 Aug 20, 11:21 HIGH PATCH This Week

Decrypted credential secrets are exposed in execution logs in n8n workflow automation software across versions before 1.123.69, 2.33.4, and 2.34.1. The GraphQL node fails to wrap connection-level HTTP client errors in n8n's standard error type, propagating raw error objects - which carry decrypted credential headers - directly into the persistent execution record. Any authenticated user with read access to workflow execution history can recover those plaintext secrets. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, but the low-privilege access requirement and direct credential exposure make this a high-priority remediation target for shared or multi-tenant deployments.

CVE-2026-74879 Aug 17, 11:04 PyPI HIGH PATCH This Week

Information disclosure in the openssl-encrypt Python pip package (jahlives/openssl_encrypt, all versions before 1.4.0) allows any unauthenticated network caller to extract sensitive database infrastructure details by hitting the /ready health-check endpoint. The endpoint returns raw Python exception strings - including database hostnames, IP addresses, port numbers, driver version, and potentially credentials embedded in connection strings - whenever a database error is triggered. No public exploit code has been identified at time of analysis, but the attack requires only a standard HTTP client and no special conditions against default deployments.

Information disclosure in Progress Telerik UI for ASP.NET AJAX before v2026.2.708 lets remote unauthenticated attackers abuse the RadAsyncUpload control's client-state handling as a cryptographic oracle. Because the server distinguishes decryption failures from invalid-JSON parse failures, an attacker can iteratively probe the encrypted rauPostData token and recover protected metadata values. No public exploit identified at time of analysis, and it is not listed in CISA KEV; EPSS was not provided.

CVE-2026-48039 Jun 11, 13:28 PyPI CRITICAL POC PATCH GHSA Act Now

Unauthenticated remote attackers can invoke MCP tool handlers and exfiltrate the operator's long-lived Meta Graph API access token from pipeboard-co/meta-ads-mcp through version 1.0.108 when the server is run with the streamable-HTTP transport on a network-reachable port. The AuthInjectionMiddleware silently forwards requests lacking an Authorization or X-PIPEBOARD-API-TOKEN header, tool handlers fall back to the META_ACCESS_TOKEN environment variable, and Graph API error responses echo the request URL - including the token query parameter - back to the caller. A working proof-of-concept is published in GHSA-9gw6-46qc-99vr; no public exploit identified at time of analysis as a separate weaponized tool, but the PoC is sufficient to reproduce end-to-end.

CVE-2026-45728 May 19, 14:35 Go HIGH PATCH GHSA This Week

Information disclosure in Algernon web server versions 1.17.6 and earlier allows unauthenticated remote attackers to retrieve full server-side source code, including embedded secrets, by triggering runtime errors in Lua, Pongo2, Amber, or HTML template handlers. When Algernon is started with a single file path (e.g. `algernon page.po2`), single-file mode unconditionally forces debug mode on, activating the PrettyError renderer which returns absolute file paths and complete file contents in HTTP 200 responses. Crucially, the `--prod` hardening flag does not block this behavior for non-`.lua` extensions, and publicly available exploit code exists in the GHSA advisory.

Infinite recursion in Vvveb admin controller exhausts PHP memory through repeated permission checks when low-privilege users access forbidden admin URLs. Sustained requests deplete worker memory causing site-wide denial of service. Fixed in version 1.0.8.3 via commit c766e84b which removes Base class inheritance from Error403 controller to break the dispatch cycle. No evidence of active exploitation but trivial to reproduce with authenticated low-privilege account.

FlightPHP Core's default error handler exposes full exception messages, stack traces, and absolute filesystem paths in HTTP 500 responses without any debug-mode gating. All versions before 3.18.1 leak internal application structure, vendor package names, and any secrets interpolated into exception messages to unauthenticated remote attackers. This information disclosure primes follow-on attacks like LFI and path traversal by revealing server paths and configuration file locations. Vendor-released patch in version 3.18.1 introduces a flight.debug setting (default false) that suppresses verbose output in production. CVSS 7.5 reflects network-accessible information disclosure with no privileges required.

CVE-2026-43873 May 05, 18:58 PHP HIGH PATCH GHSA This Week

Unauthenticated information disclosure in AVideo CloneSite plugin (versions ≤29.0) leaks the installation's shared secret authentication key through an error message, enabling attackers to impersonate the victim installation to its federated clone server and trigger a full database dump into a publicly accessible directory. The vulnerability chains two flaws: cloneClient.json.php echoes the local myKey credential in HTTP responses to any unauthenticated request due to incorrect $argv handling in web contexts, and the remote cloneServer.json.php then accepts this leaked key to authenticate mysqldump operations without IP restrictions or access controls on the resulting dump files. Patch available via GitHub commit e6566f56. No evidence of active exploitation (not in CISA KEV); EPSS data not provided. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) reflects high confidentiality impact from direct credential exposure plus cross-site database access in federated deployments.
