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-2026-11526 in the wild and no public exploit code.\n\nAffected product: RURBAN GD. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-11526/ (Markdown: https://insights.sbomify.com/CVE-2026-11526/index.md)","id":"CVE-2026-11526","markdown":"https://insights.sbomify.com/CVE-2026-11526/index.md","name":"CVE-2026-11526","record":{"aliases":["ALPINE-CVE-2026-11526","BELL-CVE-2026-11526","DEBIAN-CVE-2026-11526","GHSA-hx22-9fx3-xg77","MGASA-2026-0318","OESA-2026-2789","RHSA-2026:49758","UBUNTU-CVE-2026-11526","USN-8484-1","openSUSE-SU-2026:11017-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl GD library","requires_auth":"none","summary":"Attackers can execute arbitrary OS commands or overwrite files by passing malicious filenames to Perl GD image constructors.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"GD versions before 2.86 for Perl allow OS command injection and file overwrite via a 2-arg open() of filename arguments in _make_filehandle.\n\nGD::Image::_make_filehandle opens a filename argument with Perl's 2-arg open(), so a filename that begins or ends with a pipe (\"| cmd\", \"cmd |\") or begins with a redirect (\"\u003e path\", \"\u003e\u003e path\") is run as a command or redirect rather than opened as a file. _make_filehandle is the single open path behind every filename-accepting constructor (new, newFromPng, newFromJpeg, and the rest); the in-memory *Data variants do not open a path and are unaffected.\n\nAny caller that forwards untrusted input to one of these constructors as a pathname can run an arbitrary command or truncate a file under the process UID.","ecosystems":["Red Hat:rhel_els:7","openSUSE:Tumbleweed"],"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":"Command injection in GD","id":"CVE-2026-11526","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"Command injection in Config::IniFiles","id":"CVE-2026-11527"},"packages":[{"ecosystem":"Red Hat:rhel_els:7","fixed":["0:2.49-3.el7_9.1"],"introduced":["0"],"last_affected":[],"package":"perl-GD","purl":"pkg:rpm/redhat/perl-GD","source":"RHSA-2026:49758"},{"ecosystem":"Red Hat:rhel_els:7","fixed":["0:2.49-3.el7_9.1"],"introduced":["0"],"last_affected":[],"package":"perl-GD-debuginfo","purl":"pkg:rpm/redhat/perl-GD-debuginfo","source":"RHSA-2026:49758"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["2.860.0-1.1"],"introduced":["0"],"last_affected":[],"package":"perl-GD","purl":"pkg:rpm/opensuse/perl-GD\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:11017-1"}],"prev":{"headline":"undici vulnerable to Set-Cookie SameSite attribute downgrade via permissive substring matching","id":"CVE-2026-11525"},"products":["GD"],"published":"2026-06-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-21","vendors":["RURBAN"]},"summary":"Attackers can execute arbitrary OS commands or overwrite files by passing malicious filenames to Perl GD image constructors.","url":"https://insights.sbomify.com/CVE-2026-11526/"}
