The parser operates on raw attacker-controlled network payloads before the input is fully validated, so a single crafted message can terminate telemetry collection for the affected process or node.\n\n### Details\n\nMongoDB parsing support was introduced by commit `2070f568a` (`Add Initial support for mongodb`), so the explicit released version minimum affected is `v0.1.0`.\n\nThere are two related panic conditions in released `go.opentelemetry.io/obi` versions:\n\n- In `v0.1.0` through `v0.3.0`, `parseOpMessage` reads OP_MSG flag bits from `buf[msgHeaderSize:msgHeaderSize+int32Size]` without first ensuring the buffer is at least `msgHeaderSize + int32Size` bytes long. A truncated OP_MSG packet can therefore trigger a slice-bounds panic before the parser returns an error.\n- In `v0.1.0` through `v0.3.0`, `parseSections` consumes the section type byte and then reads the document-sequence length from `buf[offSet:offSet+int32Size]` without re-validating that enough bytes remain after the type b","public_affected_ranges":["< 0.9.0"]}],"null_published_at":"2026-11-07T07:07:39.831Z","source_updated_at":"2026-06-09T10:58:55.000Z","source_disclosed_at":"2026-05-18T20:20:03.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-06T20:56:39.448Z"}],"next_cursor":null,"snapshot_revision":"42594"}
