CVE-2026-19565 LOW Monitor

Session cookie forgery in Apache::AppSamurai::Util through version 1.01 is possible because CreateSessionAuthKey derives its entire entropy from observable runtime state - wall-clock microseconds and the Apache worker process ID - rather than a cryptographically secure random source. An unauthenticated remote attacker who can bound the second in which a target session was created and enumerate the small PID space can construct candidate 64-character hex cookies and recover a valid session token through online brute-force, bypassing authentication for all resources protected by the module. No public exploit code has been identified and SSVC confirms no current exploitation, though the attack is mechanically feasible given the constrained key space.

CVE-2026-15571 HIGH PATCH This Week

Full account takeover is possible in Keycloak's legacy client-initiated account-linking endpoint due to a predictable hash (CWE-341) used as a CSRF-like protection mechanism. An attacker who controls a registered OIDC client in the target realm can forge a valid linking URL that silently binds a victim's Keycloak account to the attacker's external identity, enabling subsequent login as the victim. No public exploit or CISA KEV listing is identified at time of analysis; Red Hat has released patches via RHSA-2026:56523 and RHSA-2026:56524.

CVE-2026-38968 CRITICAL NEWS Act Now

Session hijacking in ntopng versions through 6.6 arises because HTTP session identifiers are generated with weak, time-seeded pseudo-randomness in src/HTTPserver.cpp, making freshly issued authenticated session cookies predictable or collision-prone. Remote attackers who can influence or observe login timing can forecast a valid session token and take over an authenticated user's session without credentials. No public exploit identified at time of analysis, and EPSS is low (0.15%, 5th percentile) despite the 9.8 CVSS rating.

CVE-2026-42365 HIGH This Week

Authentication bypass in GeoVision LPC2011/LPC2211 license plate camera firmware version 1.10 allows remote unauthenticated attackers to brute-force predictable session cookies via the Web Interface and gain access to the device. The flaw stems from insufficient randomness in session token generation (CWE-341), enabling attackers to enumerate valid cookies through a crafted series of HTTP requests. No public exploit identified at time of analysis, and EPSS is low at 0.06%, but CISA SSVC rates technical impact as partial with no current exploitation observed.
