Flextype v1.0.0-alpha.3 Stored Fetch Shortcode Allows Server-Side Request Forgery
Flextype CMS v1.0.0-alpha.3's stored fetch shortcode enables server-side request forgery via attacker-controlled entry fields passed to fetch().
Flextype CMS v1.0.0-alpha.3 automatically processes attacker-controlled entry fields through its shortcode parser when global shortcode processing is enabled. The built-in fetch shortcode passes attacker-controlled resources to the server-side fetch() helper without sufficient destination restrictions. This enables stored server-side request forgery initiated from saved entry content. The issue was disclosed on the Full Disclosure mailing list on September 3, 2026.
ZDI-26-588: Fabric.js loadFromJSON Server-Side Request Forgery Vulnerability
ZDI disclosed a server-side request forgery in Fabric.js loadFromJSON (CVE-2026-19504) that can leak sensitive information from affected implementations.
Zero Day Initiative advisory ZDI-26-588 describes a server-side request forgery vulnerability in the Fabric.js canvas library's loadFromJSON function. Exploitation requires interaction with the library and attack vectors vary by implementation, potentially exposing sensitive information. The issue is rated 4.0 on the CVSS scale and tracked as CVE-2026-19504. The advisory does not report exploitation in the wild.
VU#943094: ONLYOFFICE ownCloud integration plugin contains a Server-Side Request Forgery (SSRF) vulnerability
ONLYOFFICE's ownCloud integration plugin 9.12 has an SSRF flaw (CVE-2026-84282) letting authenticated admins probe internal networks; no patch exists yet.
CERT/CC published VU#943094 for a server-side request forgery in Ascensio System SIA's ONLYOFFICE ownCloud integration plugin version 9.12, tracked as CVE-2026-84282. The /apps/onlyoffice/ajax/settings/address endpoint does not validate the user-supplied document server URL, so an authenticated administrator can make the ownCloud server send arbitrary requests to localhost and internal hosts. Differences in error responses (connection failures vs SSL/TLS errors) let attackers enumerate open and closed TCP ports for internal reconnaissance. The vendor could not be reached, so no official patch is available; CERT recommends disabling the plugin and applying egress filtering until a fix ships.
SAP Security Updates September 2026 – Critical Flaws Patched in SAP NetWeaver, Cloud and Extended Passport
SAP's September 2026 Patch Day fixes 19 notes including CVE-2026-44756 (CVSS 10.0), unauthenticated memory corruption in SAP Extended Passport Processing kernels.
SAP shipped 19 new security notes plus one update across NetWeaver, S/4HANA, Integration Suite, Commerce Cloud, and Cloud Application Programming Model. Top issues include CVE-2026-44756 (CVSS 10.0 memory corruption in SAP Extended Passport Processing across many KERNEL and Web Dispatcher versions), CVE-2026-58240 (CVSS 9.8 missing authentication in NetWeaver Message Server), CVE-2026-76969 (CVSS 9.4 credential disclosure in CAP library sap/cds-mtxs), and CVE-2026-66768 (CVSS 9.0 access control flaw in SAP GUI for Java). No exploitation is reported; organizations running affected kernels are urged to patch urgently.
CVE-2026-84501: Apache ZooKeeper: Operational log forgery via newline injection in EnsembleAuthenticationProvider
Unauthenticated attackers can forge Apache ZooKeeper operational log lines via newline injection in crafted ensemble authentication requests.
CVE-2026-84501 (moderate severity) affects Apache ZooKeeper 3.9.0-3.9.5 and 3.8.0-3.8.6. An unauthenticated attacker can inject arbitrary fake log lines into the operational log by sending a crafted add_auth("ensemble", ...) request containing newline characters. The forged entries could mislead operators or corrupt log-based monitoring and forensics.
CVE-2026-54048: Apache Impala: Avro Schema URL Server-Side Request Forgery
Apache Impala CVE-2026-54048 lets crafted Avro schema URLs trigger SSRF to internal endpoints, with responses potentially leaking via error messages.
A server-side request forgery in Apache Impala 2.0.0 through 4.5.1 on all platforms can be triggered via an Avro schema URL using an http or file:/// URI on a table. An attacker can cause Impala to send GET requests to internal endpoints it can access, and responses may be exposed through parsing error messages. Users are advised to upgrade to a fixed release.
ZDI-26-562: (Pwn2Own) Home Assistant Green mDNS Server-Side Request Forgery Vulnerability
ZDI-26-562 details an unauthenticated, network-adjacent SSRF in the Home Assistant Green mDNS server, rated CVSS 5.4 and originally demonstrated at Pwn2Own.
A server-side request forgery in Home Assistant Green's mDNS service lets network-adjacent attackers initiate arbitrary server-side requests without authentication. The Zero Day Initiative assigned the flaw a CVSS 5.4 rating under advisory ZDI-26-562. The finding originated from Pwn2Own, and no exploitation in the wild is reported.

SAP released 19 new Security Notes plus one update, fixing four critical vulnerabilities and 15 additional flaws. The most urgent is CVE-2026-44756 (CVSS 10.0), memory corruption in Extended Passport (EPP) Processing affecting many SAP Kernel and Web Dispatcher releases. Other criticals include CVE-2026-58240 (NetWeaver Message Server missing authentication, 9.8), CVE-2026-76969 (credential disclosure in CAP sap/cds-mtxs, 9.4), and CVE-2026-66768 (improper access control in SAP GUI for Java, 9.0). High-severity fixes cover XXE in Integration Suite Trading Partner Management, deserialization in NetWeaver Business Client, and memory corruption in NetWeaver AS for ABAP.
CVE-2026-87802: Apache Syncope: SRA OAuth2 JWT signature verification bypass
Low-severity CVE-2026-87802 in Apache Syncope SRA allows JWT signature forgery in OAuth 2.0 setups without JWKS URI.
CVE-2026-87802 is a low-severity improper cryptographic signature verification flaw in Apache Syncope SRA affecting versions 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.7, and 4.1.0-M0 through 4.1.2. When SRA is configured for OAuth 2.0 without a JWKS set URI assigned, an attacker can forge tokens, bypassing JWT signature verification.
