Description

This security bulletin contains information about 4 vulnerabilities.


1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2026-54048)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to disclose information from internal endpoints.

The vulnerability exists due to server-side request forgery in Avro schema URL handling when processing an avro.schema.url table property containing an HTTP or file URI. A remote user can specify a crafted avro.schema.url table property to trigger a request to an internal endpoint.

Responses may be exposed through parsing error messages.


2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2026-56207)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to impersonate another user.

The vulnerability exists due to improper verification of cryptographic signatures in the hs2-http interface during the final step of SAML2 authentication when processing bearer tokens. A remote attacker can submit a forged bearer token with an altered user name to impersonate another user.


3) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2026-57866)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: 6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to disclose secrets.

The vulnerability exists due to server-side request forgery in the ai_generate_text() function when executing the function with access to configured credential providers. A remote user can invoke the function with a known secret key to disclose secrets.

The targeted secret must be provided by a credential provider configured through the hadoop.security.credential.provider.path property in core-site.xml.


4) Incorrect authorization (CVE-ID: CVE-2026-65181)

CWE-ID: CWE-863 - Incorrect Authorization

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to execute arbitrary Java code.

The vulnerability exists due to insufficient authorization in Data Source tables when creating a table that loads an external data source class from a file uploaded to remote storage. A remote privileged user can upload a file to remote storage and create a table to execute arbitrary Java code.
