  - A improper privilege management in Fortinet FortiSandbox version 4.2.0 through 4.2.2, 4.0.0 through 4.0.2
    and before 3.2.3 and FortiDeceptor version 4.1.0, 4.0.0 through 4.0.2 and before 3.3.3 allows a remote
    authenticated attacker to perform unauthorized API calls via crafted HTTP or HTTPS requests.
    (CVE-2022-27487)

  - Cross-site scripting vulnerability in Zero-channel BBS Plus v0.7.4 and earlier allows a remote attacker to
    inject an arbitrary script via unspecified vectors. (CVE-2022-27496)

  - Improper initialization in the firmware for some Intel(R) NUC Laptop Kits before version BC0076 may allow
    a privileged user to potentially enable an escalation of privilege via local access. (CVE-2022-27493)

  - An integer underflow in WhatsApp could have caused remote code execution when receiving a crafted video
    file. (CVE-2022-27492)

  - A improper verification of source of a communication channel in Fortinet FortiOS with IPS engine version
    7.201 through 7.214, 7.001 through 7.113, 6.001 through 6.121, 5.001 through 5.258 and before 4.086 allows
    a remote and unauthenticated attacker to trigger the sending of blocked page HTML data to an arbitrary
    victim via crafted TCP requests, potentially flooding the victim. (CVE-2022-27491)
