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 Penpot?
Penpot chases Figma parity while betting on self-host and AI-agent access
Penpot is the open-source, deployment-agnostic design and prototyping tool, and its releases run on two tracks: steady Figma feature parity (background blur, design tokens, export formats) and infrastructure that sets it apart — self-hosting, an MCP server for AI assistants, and a WebGL rendering path. Development is fast and community-heavy, with each numbered release carrying dozens of enhancements and fixes.

OpenEXR
5.0DESIGN
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.
Penpot
2.5DESIGN
Penpot chases Figma parity while betting on self-host and AI-agent access
◆ Current state
Penpot is the open-source, deployment-agnostic design and prototyping tool, and its releases run on two tracks: steady Figma feature parity (background blur, design tokens, export formats) and infrastructure that sets it apart — self-hosting, an MCP server for AI assistants, and a WebGL rendering path. Development is fast and community-heavy, with each numbered release carrying dozens of enhancements and fixes.
◆ Where it's heading
Two bets run in parallel. One is closing the remaining gap with Figma feature-by-feature; the other leans into what a hosted competitor can't easily copy — private or on-prem deployment and agent-readable design files via MCP. The token-system depth and WebGL work suggest Penpot wants to be both a credible daily design tool and the default for teams that need control over where their design data lives.
◆ Prediction
Expect the parity grind to continue release-over-release, with the WebGL renderer maturing out of beta and the MCP and self-host story pushed harder as the differentiator against hosted rivals.
