{"apiVersion":"1.0","identifier":"CVE-2026-41078","description":"OpenTelemetry dotnet is a dotnet telemetry framework. In 1.6.0-rc.1 and earlier, OpenTelemetry.Exporter.Jaeger may allow sustained memory pressure when the internal pooled-list sizing grows based on a large observed span/tag set and that enlarged size is reused for subsequent allocations. Under high-cardinality or attacker-influenced telemetry input, this can increase memory consumption and potentially cause denial of service. There is no plan to fix this issue as OpenTelemetry.Exporter.Jaeger was deprecated in 2023.","publishedAt":"2026-04-23T19:17:28","lastModifiedAt":null,"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41078","cvssScore":5.9,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00222,"riskScore":0.6,"affectedProduct":"OpenTelemetry.Exporter.Jaeger","affectedVersions":"<=1.6.0-rc.1","vulnerabilityType":"Package","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-41078","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-41078","en":"https://www.redsauce.net/en/cves/CVE-2026-41078","fr":"https://www.redsauce.net/fr/cves/CVE-2026-41078","pt":"https://www.redsauce.net/pt/cves/CVE-2026-41078","de":"https://www.redsauce.net/de/cves/CVE-2026-41078","sk":"https://www.redsauce.net/sk/cves/CVE-2026-41078","el":"https://www.redsauce.net/el/cves/CVE-2026-41078"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-41078"}}
