    risk 0.59cvss 9.1epss 0.01

    A flaw was found in all versions of the Keycloak operator, before version 8.0.2,(community only) where the operator generates a random admin password when installing Keycloak, however the password remains the same when deployed to the same OpenShift namespace.

  • CVE-2026-42365HigMay 4, 2026
    risk 0.56cvss 8.6epss 0.00

    A guessable session cookie vulnerability exists in the Web Interface functionality of GeoVision LPC2011/LPC2211 1.10. A specially crafted series of HTTP requests can lead to an authentication bypas. An attacker can bruteforce session cookies to trigger this vulnerability.

  • CVE-2025-40780HigOct 22, 2025

    In specific circumstances, due to a weakness in the Pseudo Random Number Generator (PRNG) that is used, it is possible for an attacker to predict the source port and query ID that BIND will use. This issue affects BIND 9 versions 9.16.0 through 9.16.50, 9.18.0 through 9.18.39,…

  • CVE-2023-49259HigJan 12, 2024
    risk 0.49cvss 7.5epss 0.00

    The authentication cookies are generated using an algorithm based on the username, hardcoded secret and the up-time, and can be guessed in a reasonable time.

  • CVE-2026-36609HigJun 3, 2026
    risk 0.47cvss 7.3epss 0.00

    Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 uses a static authentication nonce that does not change between requests from the same source IP. Combined with the predictable XOR-based password encoding (securityEncode function), this allows an attacker to…
