What is OpenEXR?

A second IDManifest flaw lands two weeks after OpenEXR's forty-CVE sweep

OpenEXR's recent history is dominated by security response. On 2026-08-05 three branches were tagged within two minutes — v3.4.14, v3.3.13 and v3.2.11, fixing 15, 15 and 10 CVEs from one fuzzing and audit campaign, all memory corruption reachable by opening a crafted .exr file. Two weeks later v3.4.15 and v3.3.14 fix two further memory-allocation issues, this time confined to the code that decodes the idmanifest attribute, with CVEs requested but not yet assigned. The 3.4 tag also carries a missing Windows export and reduced compiler warnings in example code.

What is ProtoPie?

ProtoPie opens an MCP server, putting agents inside the prototyping tool.

Version 10.3.0 ships ProtoPie MCP in beta, following a 10.x line that has been steadily about AI inside Studio. Version 10.0.0 introduced ProtoPie AI in beta, generating triggers, responses, and logic from natural language, alongside inline annotation blocks and a redesigned formula editor with error detection. The 10.1.2 release was consolidation on that base — response reliability, onboarding, AI availability extended to the China region, and Figma element conversion into editable states. The feed itself is noisy, repeating the 10.1.2 release across several rows with differing levels of detail.

A second IDManifest flaw lands two weeks after OpenEXR's forty-CVE sweep

◆ Current state

OpenEXR's recent history is dominated by security response. On 2026-08-05 three branches were tagged within two minutes — v3.4.14, v3.3.13 and v3.2.11, fixing 15, 15 and 10 CVEs from one fuzzing and audit campaign, all memory corruption reachable by opening a crafted .exr file. Two weeks later v3.4.15 and v3.3.14 fix two further memory-allocation issues, this time confined to the code that decodes the idmanifest attribute, with CVEs requested but not yet assigned. The 3.4 tag also carries a missing Windows export and reduced compiler warnings in example code.

◆ Where it's heading

The pattern is now established: findings arrive from a continuing fuzzing effort and are patched simultaneously across every supported stream, with the release notes written to tell integrators precisely which code paths are reachable. The narrowing scope is the useful signal — August's first batch spanned the C++ libraries, the command-line tools and the Python bindings, while this one touches only idmanifest decoding and explicitly states other code is unaffected even on files carrying the attribute. Both new tags are release candidates dated ahead of their tagging, and the 3.3 backport reuses the 3.4 note verbatim, down to naming v3.4.15 in its own body.

◆ Prediction

Expect the requested CVEs to be assigned identifiers and the two RCs to be promoted to final tags, with a matching 3.2 backport if the idmanifest code is present in that stream. Further attribute-parser findings are likely while the fuzzing campaign continues.

3.8

ProtoPie opens an MCP server, putting agents inside the prototyping tool.

◆ Current state

Version 10.3.0 ships ProtoPie MCP in beta, following a 10.x line that has been steadily about AI inside Studio. Version 10.0.0 introduced ProtoPie AI in beta, generating triggers, responses, and logic from natural language, alongside inline annotation blocks and a redesigned formula editor with error detection. The 10.1.2 release was consolidation on that base — response reliability, onboarding, AI availability extended to the China region, and Figma element conversion into editable states. The feed itself is noisy, repeating the 10.1.2 release across several rows with differing levels of detail.

◆ Where it's heading

The arc from 10.0.0 to 10.3.0 is a tool teaching itself to be driven by something other than a designer's cursor. Natural-language generation of interaction logic came first, Figma conversion reduced the cost of getting existing design work in, and an MCP server exposes the prototype to external agents. Release notes for the newest versions are thin — 10.3.0 is a single line — so the shape of the MCP surface is not yet visible in the changelog.

◆ Prediction

MCP in beta usually precedes documentation of what it actually exposes; whether agents can read a prototype's state or author triggers and responses is the question the entries do not yet answer. Given the Figma conversion work, the likely direction is agents that assemble interaction logic from imported design files rather than only inspecting finished pies.
