Description
This security bulletin contains information about 7 vulnerabilities.
1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-54428)
CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to allocation of resources without limits or throttling in the HTTP/2 HPACK decoder when processing compressed header blocks before the HTTP/2 SETTINGS acknowledgement. A remote attacker can send oversized compressed header blocks to cause a denial of service.
The issue can lead to memory exhaustion before the configured header list size limit is applied.
2) Improper input validation (CVE-ID: CVE-2026-91358)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the Case management Service (11g+) component in Oracle Business Process Management Suite. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
