CVE-2026-89059 (GCVE-0-2026-89059)

Vulnerability from nvd – Published: 2026-09-18 07:13 – Updated: 2026-09-18 15:13

Title

Resteasy-core: resteasy: iioimageprovider unbounded image decode (decompression-bomb dos)

Summary

A flaw was found in RESTEasy's IIOImageProvider, which decodes attacker-supplied image request bodies without enforcing any limit on the declared image dimensions or pixel count. A remote, unauthenticated attacker can send a small crafted image declaring enormous dimensions to trigger a very large memory allocation, exhausting the JVM heap and resulting in a denial of service.

Severity

7.5 (High)

CVE-2026-89058 (GCVE-0-2026-89058)

Vulnerability from nvd – Published: 2026-09-18 07:20 – Updated: 2026-09-19 13:50

Title

Resteasy-core: resteasy: corsfilter reflects arbitrary origin with credentials under wildcard config

Summary

A flaw was found in RESTEasy's CorsFilter, which, when configured to allow all origins ("*"), reflects the request's Origin header back in the Access-Control-Allow-Origin response together with Access-Control-Allow-Credentials: true. This permissive cross-origin policy allows a malicious website to make credentialed cross-origin requests and read authenticated responses from a victim's session, resulting in a loss of confidentiality.

Severity

7.4 (High)

CVE-2026-78323 (GCVE-0-2026-78323)

Vulnerability from nvd – Published: 2026-08-24 11:11 – Updated: 2026-08-24 11:50

Title

Jss: jss: jsstrustmanager does not verify nss trust flags on ca certificates

Summary

A flaw was found in JSS (Java Security Services). The JSSTrustManager class does not verify NSS trust flags when validating CA certificates, allowing certificates present in the NSS database without TRUSTED_CA flags to be accepted as trust anchors for TLS connections. In non-default configurations where certificate revocation checking is disabled, this could allow a man-in-the-middle attacker to forge certificates accepted by PKI client connections.

Severity

6.5 (Medium)

CVE-2026-18369 (GCVE-0-2026-18369)

Vulnerability from nvd – Published: 2026-07-30 10:32 – Updated: 2026-09-14 05:28

Title

Dogtag-pki: pki-core: redhat-pki: pki: acme http-01 validation ssrf via ip literal identifiers and unvalidated redirects

Summary

A flaw was found in Dogtag PKI's ACME responder where the HTTP-01 challenge validator accepts IP address literals as dns identifiers and follows HTTP redirects without validating that the target is a public address. An unauthenticated ACME account holder can exploit this to perform server-side request forgery (SSRF), making the Dogtag server send HTTP GET requests to internal network services. With the InMemory database backend, the response body of internal targets is disclosed to the attacker through the ACME challenge error.

Severity

5.8 (Medium)

CVE-2026-18047 (GCVE-0-2026-18047)

Vulnerability from nvd – Published: 2026-07-28 12:44 – Updated: 2026-07-28 13:26

Title

Dogtag-pki: pki-core: redhat-pki: pki: acme admin enable/disable endpoint authentication bypass via trailing slash

Summary

A flaw was found in Dogtag PKI's ACME responder where the web.xml security constraints use exact URL pattern matching for admin-only enable/disable endpoints. By appending a trailing slash to the URL, an unauthenticated attacker can bypass the Tomcat authentication constraint while RESTEasy still routes the request to the handler, allowing unauthorized toggling of the ACME service state including persistent denial of service.

Severity

6.5 (Medium)

CVE-2026-17039 (GCVE-0-2026-17039)

Vulnerability from nvd – Published: 2026-07-24 15:12 – Updated: 2026-07-25 00:53

Title

Pki-core: dogtag-pki: redhat-pki: pki-core: ca renewal request processing omits realm authorization check performed by enrollment path

Summary

A flaw was found in pki-core. The certificate authority (CA) renewal request path does not perform the realm-based authorization check that the enrollment path performs, allowing an authenticated user entitled to one realm to cause a certificate belonging to a different realm to be renewed without that realm's authorization.

Severity

3.1 (Low)

This is a partial mitigation only -- it is realm-blind rather than realm-aware, so a UID collision across two independently-administered realms\u0027 user directories would still bypass it -- and it does not apply to caManualRenewal.cfg or other shipped renewal profiles that configure no authz.acl, which remain exploitable as described.

CVE-2026-89058 (GCVE-0-2026-89058)

Vulnerability from cvelistv5 – Published: 2026-09-18 07:20 – Updated: 2026-09-19 13:50

Title

Resteasy-core: resteasy: corsfilter reflects arbitrary origin with credentials under wildcard config

Summary

A flaw was found in RESTEasy's CorsFilter, which, when configured to allow all origins ("*"), reflects the request's Origin header back in the Access-Control-Allow-Origin response together with Access-Control-Allow-Credentials: true. This permissive cross-origin policy allows a malicious website to make credentialed cross-origin requests and read authenticated responses from a victim's session, resulting in a loss of confidentiality.

Severity

7.4 (High)

CVE-2026-89059 (GCVE-0-2026-89059)

Vulnerability from cvelistv5 – Published: 2026-09-18 07:13 – Updated: 2026-09-18 15:13

Title

Resteasy-core: resteasy: iioimageprovider unbounded image decode (decompression-bomb dos)

Summary

A flaw was found in RESTEasy's IIOImageProvider, which decodes attacker-supplied image request bodies without enforcing any limit on the declared image dimensions or pixel count. A remote, unauthenticated attacker can send a small crafted image declaring enormous dimensions to trigger a very large memory allocation, exhausting the JVM heap and resulting in a denial of service.

Severity

7.5 (High)

CVE-2026-78323 (GCVE-0-2026-78323)

Vulnerability from cvelistv5 – Published: 2026-08-24 11:11 – Updated: 2026-08-24 11:50

Title

Jss: jss: jsstrustmanager does not verify nss trust flags on ca certificates

Summary

A flaw was found in JSS (Java Security Services). The JSSTrustManager class does not verify NSS trust flags when validating CA certificates, allowing certificates present in the NSS database without TRUSTED_CA flags to be accepted as trust anchors for TLS connections. In non-default configurations where certificate revocation checking is disabled, this could allow a man-in-the-middle attacker to forge certificates accepted by PKI client connections.

Severity

6.5 (Medium)

CVE-2026-18369 (GCVE-0-2026-18369)

Vulnerability from cvelistv5 – Published: 2026-07-30 10:32 – Updated: 2026-09-14 05:28

Title

Dogtag-pki: pki-core: redhat-pki: pki: acme http-01 validation ssrf via ip literal identifiers and unvalidated redirects

Summary

A flaw was found in Dogtag PKI's ACME responder where the HTTP-01 challenge validator accepts IP address literals as dns identifiers and follows HTTP redirects without validating that the target is a public address. An unauthenticated ACME account holder can exploit this to perform server-side request forgery (SSRF), making the Dogtag server send HTTP GET requests to internal network services. With the InMemory database backend, the response body of internal targets is disclosed to the attacker through the ACME challenge error.

Severity

5.8 (Medium)

CVE-2026-18047 (GCVE-0-2026-18047)

Vulnerability from cvelistv5 – Published: 2026-07-28 12:44 – Updated: 2026-07-28 13:26

Title

Dogtag-pki: pki-core: redhat-pki: pki: acme admin enable/disable endpoint authentication bypass via trailing slash

Summary

A flaw was found in Dogtag PKI's ACME responder where the web.xml security constraints use exact URL pattern matching for admin-only enable/disable endpoints. By appending a trailing slash to the URL, an unauthenticated attacker can bypass the Tomcat authentication constraint while RESTEasy still routes the request to the handler, allowing unauthorized toggling of the ACME service state including persistent denial of service.

Severity

6.5 (Medium)

CVE-2026-17039 (GCVE-0-2026-17039)

Vulnerability from cvelistv5 – Published: 2026-07-24 15:12 – Updated: 2026-07-25 00:53

Title

Pki-core: dogtag-pki: redhat-pki: pki-core: ca renewal request processing omits realm authorization check performed by enrollment path

Summary

A flaw was found in pki-core. The certificate authority (CA) renewal request path does not perform the realm-based authorization check that the enrollment path performs, allowing an authenticated user entitled to one realm to cause a certificate belonging to a different realm to be renewed without that realm's authorization.

Severity

3.1 (Low)

For deployments that do use realm-based authorization, using a renewal profile that additionally restricts renewal requests to the original requester narrows exposure: the shipped caDirUserRenewal.cfg profile configures authz.acl=user_origreq=\"auth_token.uid\", which independently blocks cross-user renewal by comparing the renewing caller\u0027s UID against the UID that submitted the original request. This is a partial mitigation only -- it is realm-blind rather than realm-aware, so a UID collision across two independently-administered realms\u0027 user directories would still bypass it -- and it does not apply to caManualRenewal.cfg or other shipped renewal profiles that configure no authz.acl, which remain exploitable as described. No complete mitigation is available; apply the update once released."
