Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Origin validation error (CVE-ID: CVE-2025-7365)
The vulnerability allows a remote user to take over accounts of other application users.
The vulnerability exists due to an error in the first login flow during a IdP login. A remote user with a registered account can initiate the process to merge accounts with an existing victim's account.The attacker will subsequently be prompted to "review profile" information, which allows the the attacker to modify their email address to that of a victim's account. This triggers a verification email sent to the victim's email address. If the victim clicks the verification link, the attacker can gain access to the victim's account.
2) Improper privilege management (CVE-ID: CVE-2025-7784)
The vulnerability allows a remote user to escalate privileges within the application.
The vulnerability exists due to improper privilege management in the admin permission enforcement logic when FGAPv2 is enabled. A remote privileged user can edit their own role and gain unauthorized full access to realm configuration and user data.
3) Resource management error (CVE-ID: CVE-2025-5702)
The vulnerability allows a remote attacker to alter application's behavior.
The vulnerability exists due to an error in strcmp implementation optimized for the Power10 processor. The function writes to vector registers v20 to v31 without saving contents from the caller (those registers are defined as non-volatile registers by the powerpc64le ABI), resulting in overwriting of its contents and potentially altering control flow of the caller, or leaking the input strings to the function to other parts of the program.
4) Improper input validation (CVE-ID: CVE-2025-30749)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the 2D component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
5) Improper input validation (CVE-ID: CVE-2025-30754)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation within the JSSE component in Oracle Java SE. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
6) Improper input validation (CVE-ID: CVE-2025-50059)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Networking component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
7) Improper input validation (CVE-ID: CVE-2025-50106)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to improper input validation within the 2D component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.
