An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-48597 exists.\n\nAffected packages and fixed versions:\n- tesla (Hex): affected from 1.3.0; fixed in 1.18.3\n- tesla (Hex): affected from 1.3.0; fixed in 1.18.3\n- tesla (Hex): affected from 1.3.0; fixed in 1.18.3\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-2026-48597/ (Markdown: https://insights.sbomify.com/CVE-2026-48597/index.md)","id":"CVE-2026-48597","markdown":"https://insights.sbomify.com/CVE-2026-48597/index.md","name":"CVE-2026-48597","record":{"aliases":["EEF-CVE-2026-48597","GHSA-h74c-q9j7-mpcm"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Elixir HTTP client","requires_auth":"none","summary":"An attacker can crash the Elixir VM by exhausting the atom table through unvalidated URL schemes in Tesla.Adapter.Mint, requiring an upgrade to fix.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EEF","cpe":[{"product":"tesla","vendor":"elixir-tesla"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Allocation of Resources Without Limits or Throttling vulnerability in elixir-tesla tesla allows denial of service via atom table exhaustion in Tesla.Adapter.Mint.\n\nTesla.Adapter.Mint.open_conn/2 converts the URL scheme of every outgoing request to a BEAM atom via String.to_atom(uri.scheme) with no allow-list validation. BEAM atoms are never garbage-collected and the atom table is bounded (approximately 1,048,576 entries by default). An attacker who can influence the URL of a Tesla request — either via an application-level URL-forwarding feature (webhook, proxy, importer) or via a Location header returned by a server when Tesla.Middleware.FollowRedirects is in the pipeline — can mint one fresh permanent atom per request by varying the scheme string. After enough requests the atom table fills and the VM crashes, taking down the entire application.\n\nThis issue affects tesla: from 1.3.0 before 1.18.3.","ecosystems":["Hex"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Atom table exhaustion via untrusted URL scheme in Tesla.Adapter.Mint","id":"CVE-2026-48597","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":3,"n_references":5,"next":{"headline":"CRLF injection in Tesla.Multipart disposition parameters allows multipart part header injection","id":"CVE-2026-48598"},"packages":[{"ecosystem":"Hex","fixed":["1.18.3"],"introduced":["1.3.0"],"last_affected":[],"package":"tesla","purl":"pkg:hex/tesla","source":"EEF-CVE-2026-48597"},{"ecosystem":"Hex","fixed":["1.18.3"],"introduced":["1.3.0"],"last_affected":[],"package":"tesla","purl":null,"source":"GHSA-h74c-q9j7-mpcm"},{"ecosystem":"Hex","fixed":["1.18.3"],"introduced":["1.3.0"],"last_affected":[],"package":"tesla","purl":"pkg:hex/tesla","source":"GHSA-h74c-q9j7-mpcm"}],"prev":{"headline":"CRLF injection in Tesla.Multipart.add_content_type_param/2 allows HTTP header injection","id":"CVE-2026-48596"},"products":["tesla"],"published":"2026-06-02","related":[{"cvss_score":8.2,"headline":"Decompression bomb in Tesla.Middleware.DecompressResponse and Tesla.Middleware.Compression","id":"CVE-2026-48594","kev_date_added":null,"published":"2026-06-02"},{"cvss_score":8.2,"headline":"Authorization header leaks to third-party origin on cross-origin redirect in Tesla.Middleware.FollowRedirects","id":"CVE-2026-48595","kev_date_added":null,"published":"2026-06-02"},{"cvss_score":2.1,"headline":"CRLF injection in Tesla.Multipart.add_content_type_param/2 allows HTTP header injection","id":"CVE-2026-48596","kev_date_added":null,"published":"2026-06-02"},{"cvss_score":2.1,"headline":"CRLF injection in Tesla.Multipart disposition parameters allows multipart part header injection","id":"CVE-2026-48598","kev_date_added":null,"published":"2026-06-02"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Erlang Ecosystem Foundation","prefix":"EEF"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["elixir-tesla"]},"summary":"An attacker can crash the Elixir VM by exhausting the atom table through unvalidated URL schemes in Tesla.Adapter.Mint, requiring an upgrade to fix.","url":"https://insights.sbomify.com/CVE-2026-48597/"}
