CVE-2026-82181 Aug 28, 11:52 MEDIUM This Month

Sensitive data exposure in Le-yan's Medical Practice Management System enables access to confidential medical or patient data through URL query string parameters that persist in browser history and server or proxy log files (CWE-598). The application transmits sensitive values via HTTP GET parameters rather than POST body or secure headers, causing this data to be recorded in multiple secondary storage locations outside the intended session scope. No public exploit code has been identified at the time of analysis, but the attack class requires minimal technical sophistication once access to affected log or history files is established; medical data sensitivity elevates real-world impact beyond what the base CVSS score alone suggests.

CVE-2026-76179 Aug 27, 21:22 CRITICAL CISA Emergency

Authentication token theft and session impersonation affects the web management interface of Ebyte NE2-D11 industrial gateway firmware, where session tokens are insufficiently protected during client-side handling (CWE-598). An attacker able to observe exposed session information can capture and replay a valid token to impersonate an authenticated operator and gain full control of device management functions. The flaw carries a CVSS 4.0 score of 9.3 and was disclosed via CISA ICS-CERT (ICSA-26-237-06); no public exploit has been identified at time of analysis.

CVE-2026-63408 Aug 19, 15:53 HIGH PATCH This Week

JWT bearer token leakage in the Grav API Plugin for Grav CMS (prior to 1.0.0-rc.16) exposes valid access tokens to any party with access to server logs, proxy logs, CDN logs, browser history, or Referer headers. The JwtAuthenticator::extractBearerToken() method accepted tokens supplied via the ?token= URL query parameter on every /api/v1 route - including state-changing endpoints - rather than restricting token-in-URL to the file-download routes where it is technically necessary. An attacker who obtains a token from those secondary log sources can replay it with the full API privileges of the original token owner. No active exploitation (CISA KEV) or public exploit code has been identified at time of analysis.

CVE-2026-74880 Aug 17, 11:04 PyPI CRITICAL PATCH Act Now

Sensitive-token exposure in openssl_encrypt (the jahlives Python package, pip 'openssl-encrypt') before 1.4.0 stems from the keyserver and telemetry server accepting refresh tokens as GET query parameters. Because URLs are routinely written to server access logs, proxy/CDN logs, browser history, and forwarded in HTTP Referer headers, any party with access to those artifacts can harvest a valid refresh token and mint new access tokens, effectively bypassing authentication. Reported by VulnCheck; no public exploit identified at time of analysis and it is not on CISA KEV.

CVE-2026-66832 Aug 11, 20:49 MEDIUM CISA This Month

Session token exposure in the Mira Android app (Quanovate Tech Inc.) leaks live authentication credentials to third-party web properties and referrer logs whenever users trigger in-app WebView flows such as shop redirects. The app appends the active session token as a URL query string parameter and embeds a persistent user identifier in the WebView User-Agent header, both of which are transmitted to any destination or JavaScript context receiving that traffic. Reported by ICS-CERT under medical advisory ICSMA-26-223-01, this vulnerability affects a healthcare-adjacent platform, amplifying the sensitivity of exposed credentials; no public exploit code or CISA KEV listing has been identified at time of analysis.

Session hijacking is possible in HUMANIST Digital Human Resources (versions 26.0 through before 26.1) due to sensitive session tokens being transmitted as GET request query string parameters. Exposure occurs through server access logs, browser history, and HTTP Referer headers leaking to downstream systems. No public exploit code has been identified at time of analysis, and no CISA KEV listing exists, but the CVSS integrity and confidentiality impact ratings are both High, reflecting full session takeover potential.

CVE-2026-16207 Jul 19, 02:30 MEDIUM This Month

Sensitive API key credential exposure in django-tastypie up to 0.15.1 stems from the ApiKeyAuthentication class transmitting secrets via GET request query strings, making them visible in server access logs, proxy logs, browser history, and HTTP Referer headers. The flaw is a classic CWE-598 design error rooted in the authentication.py implementation and is remotely triggerable against any deployment using the ApiKeyAuthentication backend. No patch has been released; the project was notified via GitHub issue #1700 but has not yet responded. No public exploit code or CISA KEV listing exists at time of analysis, though the information disclosure risk is real in any environment where logs or network traffic are accessible to adversaries.

Sensitive information disclosure in IBM Engineering AI Hub 1.0.0 through 1.2.0 allows remote attackers to harvest session tokens that the application places directly in URLs, enabling session hijacking and account takeover. IBM (the reporting vendor) has released a fix; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV. The CWE-598 root cause means tokens leak passively into browser history, referer headers, proxy and server access logs rather than requiring an active attack against the server.

Session hijacking in SEPPmail Secure Email Gateway and SEPPmail Cloud before 15.0.4.2 lets an attacker who can observe traffic replay a victim's GINA web portal session because the session token is exposed both in the URL and in an HTTP header. Because the token travels in the request URL, it can leak into proxy logs, browser history, and Referer headers, enabling account takeover of the secure-message portal. There is no public exploit identified at time of analysis and the CVSS 4.0 exploit-maturity metric is 'Unproven' (E:U); the vendor CVSS 4.0 base score is 7.5.

Sensitive token exposure in the Grav CMS API plugin (getgrav/grav-plugin-api) before 1.0.0-rc.16 allows attackers to hijack valid admin sessions after JWT access tokens leak from URLs. Because JwtAuthenticator::extractBearerToken accepts tokens via the ?token= query string on every API route, those tokens are written verbatim into web server access logs, Referer headers, browser history, and upstream proxy/CDN logs, and any captured token grants full admin API access. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the CVSS 4.0 score of 8.2 reflects the high value of the leaked admin credentials.
