An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-29511 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang (Bitnami): affected all versions; fixed in 1.17.0\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-2020-29511/ (Markdown: https://insights.sbomify.com/CVE-2020-29511/index.md)","id":"CVE-2020-29511","markdown":"https://insights.sbomify.com/CVE-2020-29511/index.md","name":"CVE-2020-29511","record":{"aliases":["AZL-6449","AZL-78896","BIT-golang-2020-29511","DEBIAN-CVE-2020-29511","GHSA-g7v2-7v9m-q9j4","UBUNTU-CVE-2020-29511"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Go standard library","requires_auth":"none","summary":"Attackers can craft XML inputs causing inconsistent processing in Go applications due to namespace prefix handling flaws in the encoding/xml package.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"go","vendor":"golang"},{"product":"trident","vendor":"netapp"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-115","name":"Misinterpretation of Input"}],"description":"The encoding/xml package in Go (all versions) does not correctly preserve the semantics of element namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Other in Go","id":"CVE-2020-29511","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"golang:go","products":["golang:go"],"type":"other","year":"2020"},"n_packages":1,"n_references":2,"next":{"headline":"Unsafe tar unpacking in HashiCorp go-slug","id":"CVE-2020-29529"},"packages":[{"ecosystem":"Bitnami","fixed":["1.17.0"],"introduced":["0"],"last_affected":[],"package":"golang","purl":"pkg:bitnami/golang","source":"BIT-golang-2020-29511"}],"prev":{"headline":"Other in Go","id":"CVE-2020-29510"},"products":["Go"],"published":"2020-12-14","related":[{"cvss_score":8.1,"headline":"Microsoft Windows CryptoAPI Spoofing","id":"CVE-2020-0601","kev_date_added":"2021-11-03","published":"2020-01-14"},{"cvss_score":9.8,"headline":"Missing bound checks can lead to memory corruption in safe Go in cmd/compile","id":"CVE-2026-27143","kev_date_added":null,"published":"2026-04-08"},{"cvss_score":9.8,"headline":"Unexpected behavior from Is methods for IPv4-mapped IPv6 addresses in net/netip","id":"CVE-2024-24790","kev_date_added":null,"published":"2024-06-05"},{"cvss_score":9.8,"headline":"Arbitrary code execution via go.mod toolchain directive in cmd/go","id":"CVE-2023-39320","kev_date_added":null,"published":"2023-09-08"},{"cvss_score":9.8,"headline":"Improper handling of JavaScript whitespace in html/template","id":"CVE-2023-24540","kev_date_added":null,"published":"2023-05-11"},{"cvss_score":9.8,"headline":"Backticks not treated as string delimiters in html/template","id":"CVE-2023-24538","kev_date_added":null,"published":"2023-04-06"},{"cvss_score":9.8,"headline":"Other in go/golang","id":"CVE-2012-2666","kev_date_added":null,"published":"2021-07-09"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["Golang"]},"summary":"Attackers can craft XML inputs causing inconsistent processing in Go applications due to namespace prefix handling flaws in the encoding/xml package.","url":"https://insights.sbomify.com/CVE-2020-29511/"}
