It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45287 exists.\n\nAffected packages and fixed versions:\n- go.opentelemetry.io/otel/schema/v1.0 (Go): affected all versions; fixed in 0.0.17\n- go.opentelemetry.io/otel/schema/v1.0 (Go): affected all versions; fixed in 0.0.17\n- go.opentelemetry.io/otel/schema (Go): affected all versions; fixed in 0.0.17\n- go.opentelemetry.io/otel/schema (Go): affected all versions; fixed in 0.0.17\n- go.opentelemetry.io/otel/schema (Go): affected all versions; fixed in 0.0.17\n- go.opentelemetry.io/otel/schema/v1.1 (Go): affected all versions; fixed in 0.0.17\n- go.opentelemetry.io/otel/schema/v1.1 (Go): affected all versions; fixed in 0.0.17\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-45287/ (Markdown: https://insights.sbomify.com/CVE-2026-45287/index.md)","id":"CVE-2026-45287","markdown":"https://insights.sbomify.com/CVE-2026-45287/index.md","name":"CVE-2026-45287","record":{"aliases":["CLEANSTART-2026-LK11440","CLEANSTART-2026-NI63338","CLEANSTART-2026-YI22158","DEBIAN-CVE-2026-45287","ECHO-7401-d539-595c","GHSA-995v-fvrw-c78m","GO-2026-5281","MINI-2v72-q4fq-v5c7","MINI-5qpf-cg54-56q3","MINI-6pfh-53x8-3r7v","MINI-cm9x-2wh6-r2f5","MINI-jmq7-2pj3-hq2x","MINI-vgjm-4ffg-whfc","RHSA-2026:15859","RHSA-2026:21399","RHSA-2026:23263","RHSA-2026:25137","RHSA-2026:25238","RHSA-2026:7420","UBUNTU-CVE-2026-45287"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Go OpenTelemetry library","requires_auth":"none","summary":"Repeated schema parsing leaks file descriptors, potentially causing denial of service in long-running Go applications using OpenTelemetry.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"telemetry_schema_files","vendor":"opentelemetry"}],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-775","name":"Missing Release of File Descriptor or Handle after Effective Lifetime"},{"id":"CWE-772","name":"Missing Release of Resource after Effective Lifetime"}],"description":"OpenTelemetry-Go is the Go implementation of OpenTelemetry. Prior to version 0.0.17, `go.opentelemetry.io/otel/schema/v1.0` and `go.opentelemetry.io/otel/schema/v1.1` leaks one file descriptor on each successful `ParseFile` call. `ParseFile` opens the schema file and passes it to `Parse` without closing it; repeated parsing in a long-running process can exhaust the process file descriptor limit and cause denial of service. Exploitation depends on a consuming application exposing repeated schema parsing to an attacker-controlled path.
