OpenEXR vs Oxygen: at a glance
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 Oxygen?
The agent-driven builder is real; the beta train fixing it is still running.
Oxygen spent the 6.2 cycle opening its object model to outside AI agents, and is now four betas deep into stabilising it. The headline capability — an agent creating and editing pages, templates, Components, selectors, variables and site settings — shipped in July and has not changed since; everything after it has been correction. Beta 3 added the other substantive item of the cycle, localisation, ending the requirement to build in English.

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.
Oxygen
6.3DESIGN
The agent-driven builder is real; the beta train fixing it is still running.
◆ Current state
Oxygen spent the 6.2 cycle opening its object model to outside AI agents, and is now four betas deep into stabilising it. The headline capability — an agent creating and editing pages, templates, Components, selectors, variables and site settings — shipped in July and has not changed since; everything after it has been correction. Beta 3 added the other substantive item of the cycle, localisation, ending the requirement to build in English.
◆ Where it's heading
The release rhythm has settled into long beta trains punctuated by one directional release, and 6.2's beta run is now longer than 6.1's was. Fix areas named in the latest beta — builder, Gutenberg, MCP server — show where the agent integration is costing stability: the MCP surface is being debugged in public alongside the ordinary builder regressions. Localisation arriving mid-beta rather than at 6.2's announcement suggests scope is still being added to the train.
◆ Prediction
With Beta 4 listing fixes rather than features, an RC is the next expected step before 6.2 goes final. Whether the MCP server keeps appearing in bug-fix lists is the thing to watch — it is the part of 6.2 with no prior release history to lean on.
