Description

This security bulletin contains information about 5 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2026-58014)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/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 Third Party (glib) component in Oracle Communications Network Analytics Data Director. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.


2) Infinite loop (CVE-ID: CVE-2026-59901)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

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 improper state management in Bzip2BlockDecompressor.read() when parsing a malformed bzip2 stream. A remote attacker can send a specially crafted compressed stream to cause a denial of service.

The issue can permanently capture the event-loop thread in an infinite loop.


3) Improper input validation (CVE-ID: CVE-2026-54369)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 7.2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local authenticated user to read and manipulate data.

The vulnerability exists due to improper input validation within the Third Party (libacl) component in Oracle Communications Network Analytics Data Director. A local authenticated user can exploit this vulnerability to read and manipulate data.


4) Deserialization of Untrusted Data (CVE-ID: CVE-2026-54512)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to instantiate arbitrary classes.

The vulnerability exists due to deserialization of untrusted data in DatabindContext._resolveAndValidateGeneric() and PolymorphicTypeValidator handling when processing polymorphic type identifiers with generic parameters during deserialization. A remote attacker can supply a specially crafted type identifier and JSON data to instantiate arbitrary classes.

Only applications that accept untrusted JSON and have polymorphic typing enabled while relying on a configured PolymorphicTypeValidator allow-list are affected.


5) Improper input validation (CVE-ID: CVE-2026-41989)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 5.9 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local non-authenticated attacker to damange or delete data.

The vulnerability exists due to improper input validation within the Alarms, KPI, and Measurements (libgcrypt) component in Oracle Communications Cloud Native Core Policy. A local non-authenticated attacker can exploit this vulnerability to damange or delete data.
