  "payload": {
    "kind": "advisory",
    "title": "webkit2gtk3: Fix of 35 CVEs",
    "summary": "- Rebase to webkitgtk 2.52.3 to address WebKitGTK security advisories WSA-2026-0001 and WSA-2026-0002 (matches RHSA-2026:9692). - Drop all CVE-2025-* backport patches (Patch100..Patch112); the fixes are included in 2.52.3 upstream. - Drop fix-missing-typename.patch: target source file was removed upstream. - Adapt fix-compositemode-init.patch, fix-renderelement-binding.patch, and fix-renderflexbox-typename.patch to 2.52.3 line offsets (same semantic clang15 / libstdc++ compat fix). - Refresh all CentOS Stream 9-derived patches to the versions that ship with c9s webkit2gtk3-2.52.3 (glib-2-68, libsoup2, icu-67, g-ir-scanner-nonfatal, evolution-sandbox-warning, aarch64-build) and reorder them to match c9s so they apply with rpm's --fuzz=0 --strict mode. Our previously-carried versions targeted the 2.50.1 source tree and broke when applied against 2.52.3. - Switch build toolchain from Clang 15 to gcc-toolset-12 (GCC 12). AlmaLinux 9.2 ESU ships Clang 15 as its system compiler, but Clang 15 does not implement C++20 P0634R3 (\"implicit typename\") nor the `requires`-clause name-lookup fix needed to compile WebKit 2.52+. GCC 12 implements both and is fully supported upstream. %global toolchain is now gcc; BuildRequires updated accordingly; gcc-toolset-12 is enabled in %build via /opt/rh/gcc-toolset-12/enable. - Drop tarball signature/hash verification from %prep. Upstream's 2.52.3 .asc was signed with an expired DSA key (key expired 2026-04-14, signature made 2026-04-16), so gpgv 2.3.",
